Correct Answer: (d) 1, 2 and 3

Detailed Explanation: Statement 1 is correct: In a landmark ruling by a multi-judge constitution bench, the Supreme Court held that states possess legislative competence to sub-classify SCs and STs to ensure equitable distribution of reservation benefits to the most backward among them. Statement 2 is correct: Article 335 explicitly governs the claims of SC/ST members in public employment while balancing the mandate of administrative efficiency. Statement 3 is correct: Introduced by the 81st Constitutional Amendment Act, 2000, Article 16(4B) enables carry-forward vacancies to be treated as a distinct class, exempting them from the general 50% cap on reservations for that year.

⚠️ UPSC Prelims Trap Alert: UPSC often tests whether Article 16(4B) exemptions apply universally or only to carry-forward vacancies. It applies strictly to carry-forward unfilled vacancies.

Syllabus Match: GS Paper 2 - Indian Constitution, Historical Underpinnings, Evolution, Features, Amendments, Significant Provisions and Basic Structure.

Question 2: BRICS Architecture and Geopolitics of West Asia

Context / Statement: Consider the following statements regarding the BRICS grouping and its strategic economic architecture:

BRICS expanded recently to incorporate several new member nations, significantly increasing its footprint among major West Asian energy producers.
The New Development Bank (NDB) established by BRICS has its permanent headquarters located in Geneva, Switzerland.
India’s active engagement in BRICS complements its diplomatic objective of strategic autonomy and multi-alignment in the West Asian region.

Which of the statements given above is/are correct?

(a) 1 and 2 only
(b) 2 and 3 only
(c) 1 and 3 only
(d) 1, 2 and 3

👉 Click to Reveal Answer & Detailed Explanation

Correct Answer: (c) 1 and 3 only

Detailed Explanation: Statement 1 is correct: BRICS expanded to include countries like the UAE, Iran, and Egypt, bolstering its strategic weight in West Asian geopolitics and global energy governance. Statement 2 is incorrect: The New Development Bank (NDB) is headquartered in Shanghai, China, with regional offices like the Africa Regional Center in Johannesburg. It is not located in Geneva. Statement 3 is correct: For India, BRICS serves as an effective platform to engage constructively with nations across the Global South and balance diverse economic and strategic ties in West Asia without compromising strategic autonomy.

⚠️ UPSC Prelims Trap Alert: International financial institutions like the WTO and WHO are headquartered in Geneva, whereas BRICS' NDB is headquartered in Shanghai. Examiners frequently interchange international headquarters.

Syllabus Match: GS Paper 2 - Bilateral, Regional and Global Groupings and Agreements involving India and/or affecting India's interests.

Question 3: Quantum Computing & National Quantum Mission

Context / Statement: Consider the following statements regarding Quantum Computing and the National Quantum Mission (NQM):

Unlike classical bits that represent either 0 or 1, quantum bits (qubits) can exist in a linear combination of states known as superposition.
Quantum entanglement is a phenomenon where quantum particles become inextricably linked, allowing the state of one to instantly influence another regardless of distance, serving as the foundation for quantum cryptography.
The National Quantum Mission restricts its mandate exclusively to classical supercomputing infrastructure upgrades across premier academic institutes.

Which of the statements given above is/are correct?

(a) 1 and 2 only
(b) 2 and 3 only
(c) 1 and 3 only
(d) 1, 2 and 3

👉 Click to Reveal Answer & Detailed Explanation

Correct Answer: (a) 1 and 2 only

Detailed Explanation: Statement 1 is correct: Superposition allows qubits to process vast permutations simultaneously, giving quantum computers exponential processing advantages over classical architectures. Statement 2 is correct: Entanglement underpins secure quantum key distribution (QKD) and quantum communication networks. Statement 3 is incorrect: The National Quantum Mission (NQM) focuses on advancing quantum technologies—including quantum computing, communications, sensing, and metrology—rather than classical supercomputing (which falls under the National Supercomputing Mission).

⚠️ UPSC Prelims Trap Alert: Do not confuse the National Quantum Mission with the National Supercomputing Mission (NSM). They target completely different computational paradigms.

Syllabus Match: GS Paper 3 - Science and Technology - Awareness in the fields of IT, Space, Computers, and Quantum Technology.

Question 4: Carbon Credits Trading Scheme (CCTS) & Economic Policy

Context / Statement: Consider the following statements regarding India's Carbon Credits Trading Scheme (CCTS):

The legal architecture for the Indian carbon market and CCTS is anchored in the Energy Conservation (Amendment) Act, 2022.
Under the compliance mechanism, designated entities are assigned greenhouse gas emission intensity targets, and those emitting below target are issued Carbon Credit Certificates (CCCs).
The Bureau of Energy Efficiency (BEE), operating under the Ministry of Environment, Forest and Climate Change (MoEFCC), acts as the primary administrator for the scheme.

Which of the statements given above is/are correct?

(a) 1 and 2 only
(b) 2 and 3 only
(c) 1 and 3 only
(d) 1, 2 and 3

👉 Click to Reveal Answer & Detailed Explanation

Correct Answer: (a) 1 and 2 only

Detailed Explanation: Statement 1 is correct: The Energy Conservation (Amendment) Act, 2022 empowered the central government to specify a carbon credit trading scheme. Statement 2 is correct: Obligated entities that surpass emission reduction targets earn Carbon Credit Certificates, which can be traded with entities falling short of compliance thresholds. Statement 3 is incorrect: While BEE administers energy efficiency programs, it functions under the administrative control of the Ministry of Power, not the Ministry of Environment, Forest and Climate Change (MoEFCC).

⚠️ UPSC Prelims Trap Alert: Watch out for ministerial attribution traps. Environmental schemes are often reflexively attributed to MoEFCC, even when statutory implementation rests with the Ministry of Power or BEE.

Syllabus Match: GS Paper 3 - Indian Economy and issues relating to Planning, Mobilization of Resources, Growth, Development and Environment.

Question 5: Chola Administration & Local Self-Government

Context / Statement: Consider the following statements regarding the administrative framework of the Chola Dynasty:

The famous Uttiramerur inscriptions, belonging to the reign of Parantaka Chola, provide detailed insights into the grassroots electoral mechanism known as the *Kudavolai* system for village assemblies (*Sabha*).
Chola local administration was characterized by distinct units, including autonomous village assemblies such as *Ur*, *Sabha*, and *Nagaram*.
The Chola state exercised total centralization over internal and external trade, completely eliminating mercantile trade guilds like *Ainnurruvar* (*Manigramam*).

Which of the statements given above is/are correct?

(a) 1 and 2 only
(b) 2 and 3 only
(c) 1 and 3 only
(d) 1, 2 and 3

👉 Click to Reveal Answer & Detailed Explanation

Correct Answer: (a) 1 and 2 only

Detailed Explanation: Statement 1 is correct: Uttiramerur inscriptions provide exceptional epigraphical evidence detailing qualifications, disqualifications, and the ballot-lot system (*Kudavolai*) for selecting members to village committees. Statement 2 is correct: Chola agrarian governance featured the *Ur* (general village assembly), *Sabha* (assembly of Brahmin settlements or *Brahmadeyas*), and *Nagaram* (merchant urban centers). Statement 3 is incorrect: Far from abolishing trade guilds, the Chola era witnessed the zenith of powerful mercantile guilds like *Ainnurruvar* (The Five Hundred Swami of Aihole) and *Manigramam*, which conducted thriving maritime and overland trade across Southeast Asia.

⚠️ UPSC Prelims Trap Alert: Medieval and ancient Indian dynasties rarely exercised totalitarian economic control; dynamic trade guilds operated with considerable autonomy and royal patronage.

Syllabus Match: GS Paper 1 - Indian Heritage and Culture - History of India from Ancient to Medieval periods, Art and Architecture, Administrative Systems.
