The bell rang, the students left the classroom.

Which option fixes this comma splice error?

A.

Because the bell rang, the students left the classroom.

B.

Because the students left the classroom, the bell rang.

C.

The bell rang the students left the classroom.

(A) would fix it. It makes the most sense, it would be a cause and effect situation.

Answer: The option that fixes this comma splice error is A. Because the bell rang, the students left the classroom.

Explanation: The sentence provided contains a comma splice error because two independent clauses ("The bell rang" and "The students left the classroom") have been joined by means of a comma and no conjunction. The best way to correct this punctuation mistake is to transform one of these clauses into a subordinate clause. Option A. is the correct option because it includes a subordinate clause ("Because the bell rang") and an independent clause ("the students left the classroom") and, unlike option B., it creates a cause-and-effect relationship between the two clauses that adds coherence to the sentence.
