Step 1: Understanding the Question:
The question asks where a Public Interest Litigation (PIL) can be filed in India.
Step 2: Key Concept:
Public Interest Litigation (PIL) is a legal tool used to protect the rights of the public or a section of the public who cannot approach the court themselves. It is not litigation for private interest. The concept was developed by the Indian judiciary.
Step 3: Detailed Explanation:
A Public Interest Litigation can be filed directly in:
1. The Supreme Court of India under Article 32 of the Constitution (Right to Constitutional Remedies).
2. The High Courts of various states under Article 226 of the Constitution.
A PIL cannot be filed in a District Court or other subordinate courts. Since both the High Court and the Supreme Court are correct options, and no 'both' option is available, this is a poorly framed question. However, both courts have the jurisdiction. If only one can be chosen, either could be considered correct as both are primary venues for filing PILs. Let's note that jurisdiction exists for both.
Step 4: Final Answer
A Public Interest Litigation can be filed in both the High Court and the Supreme Court. The question as framed is ambiguous, but both (A) and (B) are factually correct.
