UGC NET Questions (Paper – 1)

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.

Statements A, B, C and E are correct and collectively show the range of climate–health linkages. Heatwaves and shifting disease vectors affect health, climate-resilient planning strengthens systems and vulnerable groups face disproportionate risks. Statement D is wrong because air quality policies are central to climate mitigation and co-benefits, and F is wrong since health co-benefits are a strong argument for mitigation in policy debates. Therefore, the correct combination is A, B, C and E only.

Option A:
Option A is incorrect as it omits E, failing to acknowledge that certain social groups are more at risk. Without E, the distributional and equity dimensions of climate–health impacts are not reflected.

Option B:
Option B is incorrect because it includes D, which wrongly claims air quality is unrelated to climate policy. Including D introduces a serious conceptual error about the links between air pollution control and climate mitigation.

Option C:
Option C is incorrect since it comprises B, C, E and F, accepting F as if health co-benefits were irrelevant. In reality, such co-benefits are often used to justify stronger mitigation policies, so this option mixes correct and incorrect statements.

Option D:
Option D is correct as it assembles all the true statements and excludes the two clearly false ones. It reflects current understanding that climate change affects health through multiple pathways and that vulnerability and system resilience are key concerns.
