Section 100 of the Indian Penal Code, 1860, lists a fixed set of situations in which the right of private defence of the body extends to voluntarily causing the death of the assailant. Testing each option against that list shows which situation actually qualifies.
- Option (A): An assault committed with the specific intention of kidnapping or abducting a person is one of the offences named in Section 100. The clause treats the threat of being kidnapped or abducted as serious enough that the person under attack may use force extending to death to resist it, without waiting to see if greater harm follows.
- Option (B): Criminal trespass on open, vacant land concerns the right of private defence of property, governed by Section 103, and even there such trespass does not, by itself, justify causing death because it is not among the aggravated forms of trespass, such as trespass by night on a building used as a dwelling, that Section 103 recognises for that purpose. It has no application to the body at all.
- Option (C): A simple assault carried out without a weapon does not create the reasonable apprehension of death or grievous hurt that Section 100 requires before the right can extend to killing the assailant. Ordinary force in response is justified, but not a fatal one.
- Option (D): Theft is again a property offence, dealt with under Section 103, and the right there may extend to death only in narrow situations such as theft accompanied by house-breaking by night, not merely because the value of the stolen property crosses a monetary figure such as ₹10,000.
Only the situation in option (A) is one of the specific circumstances Section 100 recognises as justifying death in defence of the body.
Therefore, the correct answer is An assault committed with the specific intention of kidnapping or abducting a person.
