Model Answer
Answer: B
Assertion (A) is true — environmental degradation consequences cross national boundaries, making sustainable development essential. Reason (R) is false — crude oil is a non-renewable resource that will be exhausted; world reserves will last only about 47 years at current extraction rates.
Explanation
- A is directly supported by the passage: "Consequences of environmental degradation do not respect national or state boundaries."
- R is clearly false: the passage states non-renewable resources "will get exhausted after a few years of use" and crude oil reserves will last only ~47 years globally — the opposite of "unlimited."
- Since R is false, it cannot explain A, so option B is correct.
