Under Section 6 of the IPC, every definition and penal provision in the Code is to be understood:

1. Section 6 IPC reads: 'Throughout this Code every definition of an offence, every penal provision, and every illustration of every such definition or penal provision, shall be understood subject to the exceptions contained in the Chapter entitled General Exceptions, though those exceptions are not repeated in such definition, penal provision, or illustration.' 2. The 'General Exceptions' are in Chapter IV (Sections 76-106): mistake of fact, judicial act, accident, necessity, infancy, insanity, intoxication, consent, private defence, etc. 3. Hence Section 6 imports those exceptions into every offence by reference. 4. Customs or usages do NOT override the IPC unless saved by another statute. 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 6 (General Explanations)_
