Explanation:

Let’s break it down:

- Section 297 Cr. P.C.

This is the one that lays out who can swear affidavits in criminal courts. Judges, Magistrates, and other authorized legal officers can take affidavits under this section.

- Section 387 Cr. P.C.

This deals with how appellate courts handle cases when they want to hear more evidence—not about affidavits at all.

- Section 280 Cr. P.C.

This one talks about the Magistrate’s power to record remarks on witness demeanour during a trial, nothing about affidavits.

- Section 289 Cr. P.C.

This relates to procedures about accused persons when evidence is to be taken, especially in summons cases. Again—not about affidavits.

So, the right answer is Option 1: Section 297 of the Cr. P.C.—that’s the one about authorities for affidavits.
