Under the provisions of the Indian Evidence Act, 1872, confession before a police officer by the accused in the custody of the police officer becomes relevant, if

Under the Indian Evidence Act, 1872, confessions made to police officers (Section 25) or while in police custody (Section 26) are generally inadmissible. However, Section 27 acts as a proviso to these rules. It states that when any fact is deposed to as discovered in consequence of information received from a person accused of any offence, in the custody of a police officer, so much of such information, whether it amounts to a confession or not, as relates distinctly to the fact thereby discovered, may be proved.

This is often referred to as the "Doctrine of Confirmation by Subsequent Events." For the information to be relevant, there must be a direct causal link between the information provided and the subsequent discovery of evidence (like a weapon or stolen property). Options A and B are irrelevant to the admissibility of a confession under the Act.
