The correct answer is D.
Article 48(A) of the Indian Constitution is a directive principle of state policy. It states that the State shall endeavor to protect and improve the environment and safeguard the forests and wild life of the country.
Directive principles of state policy are not enforceable in a court of law, but the State is expected to follow them in making laws and policies.
The other options are incorrect because:
- Option A is incorrect because Article 48(A) is a directive principle of state policy, not a power of the state government.
- Option B is incorrect because Article 48(A) is a directive principle of state policy, not a power of the Union government.
- Option C is incorrect because Article 48(A) is not a fundamental right of the Indian citizen.
