In Section 109 IPC, the abettor of an offence — when the act abetted is committed in consequence — is punished with:

1. Section 109 IPC: 'Whoever abets any offence shall, if the act abetted is committed in consequence of the abetment, and no express provision is made by this Code for the punishment of such abetment, be punished with the punishment provided for the offence.' 2. Hence abettor and principal are punished alike, unless the IPC specifically provides differently. 3. Sections 110-117 IPC deal with variations: e.g. when the act done is different from the act abetted (110), when the consequence is probable (111), etc. 4. The rationale is that the abettor's culpability is morally equivalent to the principal's. 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 109_
