50.
The answer is: C
Explanation
The correct option is C: Section 151.
According to Section 151 of the Indian Evidence Act, 1872, the court may forbid any questions or inquiries which it regards as indecent or scandalous, unless they relate to facts in issue, or to matters necessary to be known in order to determine whether or not the facts in issue existed.
This section confers power upon the court to prevent any question that is obscene or dishonorable in the opinion of the court, even if it has some bearing on the questions before the court.
Such questions may be put to the witness during cross-examination, but only when they are relevant to the facts in issue or are necessarily connected with them. The purpose of this section is to protect the dignity and reputation of the witness and to maintain the decorum of the court.
