Environmental standards and monitoring – UGC NET Question

Statements A, B, C and E are correct because standards exist for air, water and noise, and regular monitoring is required to see whether actual conditions meet these limits. Statement D is false, since even legally binding standards require regulatory institutions, penalties and compliance mechanisms to be effective. Statement F is false too because public disclosure of data supports transparency and can create pressure for better enforcement. Therefore, the set that keeps A, B, C and E while excluding D and F is correct.

Option A:
Option A is incorrect as it omits E and thereby ignores the crucial role of monitoring in making standards meaningful. Without E, there is no way to check compliance systematically.

Option B:
Option B is incorrect since it leaves out C, thus failing to mention noise standards, which are part of environmental quality frameworks, especially in urban areas.

Option C:
Option C is incorrect because it includes D, which wrongly suggests that standards never need enforcement mechanisms. Including D mixes a clearly false claim with correct statements.

Option D:
Option D is correct as it retains all the true statements about what standards are and how they are applied, while rejecting the idea that enforcement and public information do not matter.
