The first one is correct, the second is also correct, and the third one isn't correct.

The answer you selected for $C^{\prime}$ is actually the set $C$ itself.  In the problem there, they told you $C$ was the set of positive odd numbers.  Hence, the complement of $C$ (i.e. $C^{\prime}$) should be the set of positive numbers that isn't odd.  So that now begs the following question: if the number isn't odd, then it has to be what?

Do you think you can take things from here? :-)
