Which of the following is not correct?
a The students completed their classwork and went out to play.
b. The students completed their classwork, and went out to play.

Respuesta :

A is wrong, because and is one of the FANBOYS, and needs a comma

Answer:

B

Explanation:

B is not correct because the two parts of the sentence is seperated by a conjunction. "And." Therefore, it does not need a comma, because the sentence is already seperated.
