How many friends . . . . . . she . . . . . ? A. do , have B. does , has C. does , have D. are , has

The correct answer is: B. does, has

The subject of the sentence is “she”, which is singular. Therefore, the verb “to have” should also be singular. The verb “to do” is used with plural subjects, so it cannot be used in this sentence.

The answer “C. does, have” is incorrect because the verb “to have” should be singular.

The answer “D. are, has” is incorrect because the verb “to be” is used with plural subjects, and the verb “to have” should be singular.
