Correct option is A
An inquest proceeding under Sections 194-196 of the Bharatiya Nyaya Sanhita (BNS), 2023, is an investigation conducted by the police or magistrate to determine the cause of death under suspicious circumstances. It involves examining the scene of the death, gathering evidence, and recording witness statements to ascertain the facts surrounding the death. It is distinct from a judicial enquiry (Option B), body identification (Option C), or merely sending the body for post-mortem (Option D). Thus, the correct answer is (a).
