The right of private defence of body extends, under Section 100 IPC, to the voluntary causing of death of the assailant if the assault is of any of the descriptions specified, including:

1. Section 100 IPC enumerates SEVEN situations in which the right of private defence of the body extends to causing death: (i) assault reasonably causing apprehension of death; (ii) assault reasonably causing apprehension of grievous hurt; (iii) assault with intent to commit rape; (iv) assault with intent to gratify unnatural lust; (v) assault with intent to kidnap or abduct; (vi) assault with intent to wrongfully confine; (vii) act of throwing or attempt to throw acid (added by Criminal Law (Amendment) Act, 2013). 2. The threshold is OBJECTIVE reasonable apprehension, not subjective fear. 3. Mere verbal abuse without imminent assault is not covered. 4. Section 99 lists restrictions: e.g. no right of private defence against public servants acting lawfully, no more harm than necessary. 5. Hence option B is correct. _Source: Indian Penal Code 1860 / Code of Criminal Procedure 1973 / Indian Evidence Act 1872 (Bare Acts, indiacode.nic.in) — IPC, Section 100 (seven enumerated grounds)_
