Given below are two statements: Assertion [A]: Climate change is leading to an increase in social tension in India. Reason [R]: The frequency and intensity of the extreme weather events will have serious repercussions on food security. Choose the correct answer from the code given below:

Both statements are true, and the reason explains the mechanism behind the assertion. Climate change is raising the frequency of droughts, floods, heatwaves and erratic monsoons, which hit rainfed agriculture hardest. When crop output falls, food prices rise, rural incomes shrink and distress migration follows. This pressure on livelihoods, water and land is a known driver of local conflict, so the chain runs from climate change to food insecurity to social tension.

Why the others fail: Option B denies the causal link, but food insecurity is the channel through which climate stress becomes social stress. Options C and D are wrong because the reason is a sound, widely cited claim in IPCC assessments and Indian climate reports.

Core concept: climate-induced livelihood stress as a threat multiplier. Mains angle: GS-III on climate adaptation and food security, and GS-I on migration and rural-urban tensions.

Trap: candidates treat the reason as not directly about social tension and choose B, without asking whether food insecurity is the mechanism linking the two.
