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.

<em><u>C is the correct answer.</u></em><em><u /></em><u />
D is wrong because it has Don't which is a contraction for "Do not" and it also has nobody.
