The answer is: A
Explanation
The correct option is A: must relate to the cause of his own death.
Explanation:
Under Section 32 of the Indian Evidence Act, 1872, a statement made by a person who is dead is admissible as evidence if it relates to the cause of the person's own death. The section specifically states that statements by a person who is dead, in cases in which the cause of that person's death comes into question, are relevant. This means that the statement must directly pertain to the circumstances or cause of the person's own death to be admissible.
Options B and C are not entirely accurate. While it is true that a statement may relate to the cause of someone else's death under certain circumstances, the primary focus of Section 32 is on statements regarding the cause of the declarant's own death. Therefore, the correct interpretation is that the statement must relate to the cause of the declarant's own death, making option A the correct choice.
