The answer is: C
Explanation
The correct option is C: Doctrine of confirmation.
According to the Law Commission of India 69th Report, section 27 of the Indian Evidence Act is based on the doctrine of confirmation by subsequent facts.
This doctrine means that if any fact is discovered as a result of information given by the accused in custody, such discovery confirms the truth of the information and makes it admissible as evidence.
The doctrine is founded on the principle that a person who gives true information is unlikely to be a false confessor, and that the discovery of a fact in consequence of such information proves that he is privy to the crime.
The doctrine also ensures that only the relevant and reliable part of the information is admitted, and not the whole confession or statement of the accused.
