The answer is C.

Explanation: Contrapositive of some statement is a statement that has negations in it. This kind of statement you can write in a form: If A than B. Contrapositive of this would be: If not A than not B. Now you need to look in possible answers and check them out.

-In first statement we negated A but not A

-In second we negated A but not B (the difference is that A and B have different order

-In forth B is negated while A isnt.

Finally if we check C we see that it matches. Both A and B are negated.
