Read the given sentence, which is divided into four parts marked (A), (B), (C), and (D), and choose the segment that contains a grammatical error. If there is no error in the sentence, select 'No error' as your answer.

The committee have (A)/ begun reviewing (B)/ the proposal for the new community center (C)/ set to open in the city next summer. (D)

The correct option is A.

Explanation:
In segment (A), "The committee have", there is a subject-verb agreement error.

The word "committee" is a collective noun referring to a single group acting as a unified entity. In standard English grammar, when a collective noun acts in unison as a single unit, it requires a singular verb. Therefore, the plural auxiliary verb "have" must be replaced with the singular verb "has".

Corrected Sentence:
"The committee has begun reviewing the proposal for the new community center set to open in the city next summer."
