Step 1: Understanding the Case.
In *D.C. Wadhwa Vs State of Bihar*, the Supreme Court held that a member of the public, having sufficient interest, could maintain a petition under Article 32 of the Constitution. The case involved the issue of the Bihar government re-promulgating ordinances without legislative approval, and the Court accepted the petitioner's standing to challenge this practice.
Step 2: Explanation of Other Options.
- (a) Parmanand Katara Vs Union of India concerns medical treatment for the injured, and does not directly relate to standing under Article 32 for public interest.
- (c) Neeraja Choudhari Vs State of Madhya Pradesh deals with election law and does not involve standing under Article 32 in the same context.
- (d) Chameli Singh Vs State of U.P. is a case dealing with land acquisition and not with the standing of a member of the public under Article 32.
Step 3: Conclusion.
The correct case is *D.C. Wadhwa Vs State of Bihar*, where the Court recognized the right of an individual with sufficient interest to approach the Court under Article 32.
