Question #N190

Which choice correctly punctuates the following sentence? The large, red ball bounced across the room until it hit the wall and stopped.
A. The large, red ball bounced across the room, until it hit the wall, and stopped.
B. The large, red ball bounced across the room, until it hit the wall and stopped.
C. The large, red ball bounced across the room until it hit the wall and stopped.
D. The large, red ball bounced across the room until it hit the wall; and stopped.

Correct Answer is: C

The sentence is a complex sentence, and the comma correctly separates the independent clause from the dependent clause. The comma is not needed after 'wall' because the dependent clause is essential to the meaning of the sentence.
