Climate change and human health effects – UGC NET Question

Statement C is clearly wrong because climate change can affect food production, availability and access, which in turn influences nutrition and health. Statements A, B and D are correct as they reflect established links between heatwaves and mortality, climate-sensitive disease vectors and disruption of health systems by extreme events. Since only C is incorrect, the combination that identifies C alone as wrong is the correct answer.

Option A:
Option A is incorrect because it treats both A and C as wrong, whereas statement A is accurate. Rising temperatures and more frequent heatwaves are associated with heat stress, dehydration and increased mortality, especially among vulnerable groups. Including a correct statement in the wrong set makes the option unacceptable.

Option B:
Option B is incorrect because it marks both C and D as wrong. While C is wrong, D is correct since floods, storms and other extremes can damage hospitals, supply chains and health infrastructure. Misclassifying D as wrong contradicts disaster and health studies.

Option C:
Option C is incorrect because it claims A, C and D are all wrong. A and D are correct descriptions of climate-related health impacts. By placing them in the wrong set, this option conflicts with widely accepted scientific assessments.

Option D:
Option D is correct because it isolates statement C as the only incorrect statement. It acknowledges that climate change can and does influence food security and nutrition, which C wrongly denies, while recognising that A, B and D accurately describe other health impacts.
