Meet or Met?

Is this correct?

1. A: Have you ever met him?

B: No, I have not met him.

The Answer.

1. “Met”here is used as a past participle and is part of the present perfect negative verb “have not met”. The answer is in the present perfect tense because the question is in that tense, using the verb “have met”. It would be better to use the adverb “never” in the answer instead of “not”, because the question uses the adverb “ever”. Thus the dialogue would go:

A : Have you ever met him?

B : No, I have never met him.
