Correct option is C
In Vardhaman Kaushik v. Union of India (2014–15), the National Green Tribunal (NGT) dealt with the issue of severe air pollution in Delhi. The NGT adopted a pragmatic, consultative, and deliberated approach to tackle pollution, rather than rejecting the petition on technical grounds. The tribunal issued several directives such as controlling vehicle emissions, construction dust, and crop burning. Hence, (B) only is correct.
