The correct answer is (c).
Section 13 of the Indian Evidence Act, 1872 deals with the plea of alibi. It states that when a person is accused of an offence, he may plead that he was at some other place at the time of the commission of the offence. If the plea is proved, it is a good defence to the charge.
The plea of alibi can be raised by the accused either in his examination-in-chief or in his cross-examination. If the accused raises the plea in his examination-in-chief, the prosecution has to prove that the accused was at the place of the offence at the time of the commission of the offence. If the accused raises the plea in his cross-examination, the prosecution has to prove that the accused was not at the place where he claims to have been at the time of the commission of the offence.
The plea of alibi is a very important defence in criminal law. It can be used to establish the innocence of the accused. However, it is important to note that the plea of alibi is not a complete defence. The accused has to also prove that he was not at the place of the offence at the time of the commission of the offence.
The other options are incorrect because they do not deal with the plea of alibi.
