UPSC Prelims 2015— Question 38

Correct answer: Option D. The Andaman and Nicobar Islands have exceptionally diverse tropical vegetation. Their forests include mangrove formations, evergreen forests and deciduous elements because of variations in rainfall, soils, topography and coastal conditions. The other regions listed do not provide the same combination at the scale and ecological distinctiveness indicated in the question. Option-wise analysis: Option A: “North Coastal Andhra Pradesh” 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: “South-West Bengal” 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: “Southern Saurashtra” 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 D: “Andaman and Nicober Islands” is correct. It directly matches the factual or conceptual requirement tested by the question and is supported by the principle explained above. 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.
