Official UPSC Answer KeyUPSC Prelims 2023 • Environment and Ecology

Correct Answer: Option (C) — Statement-I is correct but Statement-II is incorrect

Concept & Option Breakdown

Standard Reference Verified

Statement-I is correct: Native wild populations of marsupials (pouched mammals) are confined to Australasia and the Americas (e.g., kangaroos, koalas, opossums). They are not naturally found in India. Statement-II is incorrect: Marsupials inhabit diverse biomes including tropical forests, arid deserts, scrublands, and temperate woodlands, and they regularly coexist with natural predators such as dingoes and birds of prey.

Elimination Heuristic & Exam Approach

Extreme keyword rule: Statement-II contains 'can thrive only in', which makes it highly restrictive and statistically likely to be incorrect.
