Which sentence uses negative words correctly? a. nobody should say nothing during the test. b. never leave a dog in no car on a hot day. c. we had barely gotten in the car when it started to pour. d. don't let nobody eat before dinner.

A is wrong because it has Nobody and nothing in the same sentence. That makes the meaning of the sentence confusing because there are too many negatives.

Same goes for B. B has Never and no in it. Double negatives.

C is the correct answer.

D is wrong because it has Don't which is a contraction for "Do not" and it also has nobody.

Hope that helps :)
