Mark the correct statement:

The questions which are put only to test the credibility of a person will not be allowed as interrogatories, although they may be asked in cross-examination

Interrogatories can be administered only to a party to a suit and not to a witness, whereas cross-examination can be of any person, parties and witness alike

A party filing affidavit in reply to interrogatories can neither cross-examine nor adduce evidence to contradict it, as it is a conclusive proof
