A struck her husband B a single blow on his head with a roller pin. B fell down bleeding from his nose and became senseless. A, thinking that B was dead, hung him with a piece of rope from the ceiling which actually caused B’s death. A is guilty of:

Correct option is C

Under Section 101 of the Bharatiya Nyaya Sanhita (BNS), 2023 (formerly Section 300 IPC), an act constitutes murder if it is committed with the intention of causing death or with the knowledge that the act is so imminently dangerous that it would likely cause death.

In this case:

1. A struck B on the head with a roller pin, which caused him to fall senseless and bleed.
2. A, believing B to be dead, hung him from the ceiling with a rope.
3. The act of hanging B, despite being based on a mistaken belief, showed A's clear intention to ensure B’s death, making it murder under Section 302.

The initial blow could be construed as causing grievous hurt, but the act of hanging B, which directly led to his death, makes A guilty of murder.
