Explanation:

- An affidavit is a written statement confirmed by oath or affirmation, used as evidence in court.

- Option 1: To satisfy the court about the authenticity of the allegations made in the affidavit.

- Verification of an affidavit ensures that the court trusts the truthfulness of the claims being made.

- Option 2: To make the deponent accept responsibility for the same.

- When a deponent verifies an affidavit, they are essentially promising that the information provided is true to the best of their knowledge, thus holding themselves accountable.

- Option 3: Both (A) and (B).

- Correct! Both the authenticity of the allegations and the deponent's accountability are required by law for effective legal proceedings.

- Option 4: None of these.

- This would imply that verification is not necessary for these purposes, which is incorrect.
