Step 1: Understanding Public Interest Litigation.
Public Interest Litigation (PIL) can be filed under Article 32 (in the Supreme Court) and Article 226 (in the High Court) of the Indian Constitution. These provisions allow citizens to approach the Court for the enforcement of fundamental rights or other public matters.
Step 2: Explanation of Other Options.
- (b) U/s. 133 of the CrPC is related to Magistrate's powers to take cognizance of public nuisance and does not directly relate to PILs.
- (c) is incorrect since the correct answer is (a).
Step 3: Conclusion.
PIL can be filed under Article 32 and Article 226 for enforcement of fundamental rights and public issues.
