Explanation
The correct option is B: Section 154.
FIR stands for First Information Report, which is the earliest and the first information of a cognizable offence recorded by an officer-in-charge of a police station.
According to Section 154 of the Code of Criminal Procedure (CrPC), any person who has knowledge of the commission of a cognizable offence can give such information orally or in writing to the officer-in-charge of a police station. The officer-in-charge is then required to reduce the information into writing, read it over to the informant, and enter it in a book to be kept by such officer. The informant can also sign the written document and receive a copy of it. This document is known as the FIR, which sets the criminal law in motion and starts the investigation.
