Section 511 IPC provides punishment for attempts to commit offences. The punishment is:

1. Section 511 IPC: 'Whoever attempts to commit an offence punishable by this Code with imprisonment for life or imprisonment, or to cause such an offence to be committed, and in such attempt does any act towards the commission of the offence, shall, where no express provision is made by this Code for the punishment of such attempt, be punished with imprisonment of any description provided for the offence, for a term which may extend to one-half of the imprisonment for life or, as the case may be, one-half of the longest term of imprisonment provided for that offence, or with such fine as is provided for the offence, or with both.' 2. So the maximum punishment for an attempt is HALF the maximum for the completed offence. 3. Some IPC provisions (e.g. Section 307 — attempt to murder, Section 308 — attempt to commit culpable homicide) make express attempts substantive offences with their own punishments, bypassing Section 511. 4. Hence option B captures the half-rule of Section 511 correctly. _Source: Indian Penal Code 1860 / Code of Criminal Procedure 1973 / Indian Evidence Act 1872 (Bare Acts, indiacode.nic.in) — IPC, Section 511_
