Answer:

Subject-verb agreement: subject and verb has to match

Explanation:

It is a) because the answer choice's verb (has) matches the subject (activist).

Activist is a singular noun, so the verb must be for singular nouns.

He has, she has, the book has, the activist has, etc.

The second one uses the word "have," which is for plural nouns/pronouns denoting more than one person/thing.

They have, we all have, the activists have, etc.
