Correct option is C
As per Section 180 of BNSS, statements made by any person to a police officer during an investigation shall not be signed by the person making it. These statements are not admissible as substantive evidence in court but can be used to contradict the witness's testimony during the trial, in the manner provided by Section 148 of BSA. This ensures that such statements are used only for limited purposes, primarily for contradiction, and not as direct evidence.
