Food security and environmental sustainability – UGC NET Question

Statements B, C and D are correct because they show that food security is influenced by climate impacts, sustainable practices and multiple dimensions beyond sheer output. Climate extremes affect yields, sustainable agriculture balances productivity and environmental health and food security includes access and nutrition. Statement A is incorrect since national production alone does not guarantee that people can access or afford adequate, nutritious food. Therefore, the combination that includes B, C and D and excludes A is the correct answer.

Option A:
Option A is incorrect because it leaves out D, which correctly emphasises access and nutritional quality as core components of food security. Restricting the concept to production and climate-impacted yields fails to capture the full meaning of food security.

Option B:
Option B is incorrect as it adds statement A, which wrongly claims that only total national production matters. By including A, this option accepts a narrow and misleading view of food security that ignores distribution and affordability issues.

Option C:
Option C is incorrect because it declares all four statements A, B, C and D to be correct. Since A is clearly false in light of the multidimensional definition of food security, this combination cannot be accepted.

Option D:
Option D is correct because it lists exactly those statements that align with widely accepted definitions of food security and environmental sustainability. It highlights climate effects, sustainable agricultural responses and the multi-dimensional nature of security, while rejecting the simplistic production-only view in A.
