UGC NET Questions (Paper – 1)

Statements A, B, D and E are correct because agrobiodiversity covers crops, livestock and associated species, genetic diversity improves resilience, on-farm conservation preserves varieties and dietary diversity relies on a range of species and products. Statement C is wrong since monocultures often reduce resilience by narrowing genetic bases, and F is wrong because seed and gene banks are central ex situ tools for conserving agricultural biodiversity. Thus, the correct combination must include A, B, D and E while excluding C and F.

Option A:
Option A is incorrect because it lists only A, B and D and omits E, thereby ignoring the important link between diversity on farms and diversity on plates. Since dietary diversity is a widely recognised outcome of agrobiodiversity, leaving out E makes the answer incomplete.

Option B:
Option B is incorrect as it includes C, which wrongly asserts that monocultures always enhance resilience, and omits E. Accepting C contradicts evidence that genetically uniform systems can be highly vulnerable to shocks, so this combination mixes valid and invalid statements.

Option C:
Option C is correct since it gathers all four true statements about the roles and implications of agrobiodiversity and excludes the two that misrepresent monoculture effects and the role of gene banks. It provides a balanced view encompassing production, resilience, conservation and nutrition.

Option D:
Option D is incorrect because it includes F, which treats gene banks as irrelevant, even though they are key institutions for conserving genetic resources, and omits A, which defines agricultural biodiversity itself. As a result, this option fails both on definition and on conservation mechanisms.
