Which sentence is grammatically correct?
Show answer & explanation
Correct answer: C
Explanation
(A) is incorrect because "Each" is a singular subject and requires a singular verb ("is" or "was").
(B) is incorrect because "Every boy and girl" is a singular subject and requires a singular verb ("has").
(C) is correct; "Either" is a singular subject and correctly uses the singular verb "is".
(D) is incorrect; in "neither...nor" constructions, the verb agrees with the subject closest to it. "Friends" is plural, so the verb should be "are".
