The pupil was asked to rectify the mistake.

The correct answer is A. correct.

To rectify something means to make it right or to correct it. In this case, the pupil was asked to correct the mistake they had made.

The other options are not correct because they do not mean the same thing as rectify.

• To condone something means to forgive or overlook it.
• To clarify something means to make it clearer or to explain it.
• To repeat something means to say or do it again.

I hope this helps!
