UPSC Prelims 2015— Question 64

Correct answer: Option C. Mekong-Ganga Cooperation brings together India and five Southeast Asian countries: Cambodia, Laos, Myanmar, Thailand and Vietnam. Bangladesh and China are not participants. Among the listed countries, Bangladesh and China are therefore the non-participants, corresponding to the combination represented by the correct option. Option-wise analysis: Option A: “1 only” is incorrect. It does not match the specific fact, definition, institutional role, geographical association, or constitutional/economic principle required here. The key distinction is the one identified in the core explanation, so this option can be eliminated. Option B: “2, 3 and 4” is incorrect. It does not match the specific fact, definition, institutional role, geographical association, or constitutional/economic principle required here. The key distinction is the one identified in the core explanation, so this option can be eliminated. Option C: “1 and 3” is correct. It directly matches the factual or conceptual requirement tested by the question and is supported by the principle explained above. Option D: “1, 2 and 5” is incorrect. It does not match the specific fact, definition, institutional role, geographical association, or constitutional/economic principle required here. The key distinction is the one identified in the core explanation, so this option can be eliminated. Prelims takeaway: Focus on the precise institutional role, constitutional provision, geographical association, or technical definition being tested. UPSC questions often place a broadly familiar fact beside a narrowly incorrect qualifier; identifying that qualifier is essential for elimination.
