For those who picked A: you fell into the  trap ! 
When you have two positive integers, the classic trap answer is that  you assume they are different .

So whenever you have a question mentioning just about   two integers   think of two cases : 
1- The integers are different 
2- The integers are the same

Here if the integers are different statement 1 would be sufficient, but it is not mentioned anywhere. So the integers could actually be the same and thus  Statement 1 is not sufficient!

The low hit rate on this question is resulting from the fact that this question is flawed.

The question says that X and N are "two positive integers."

If they are "two positive integers" they have to be different. If they were the same number, they would not be two positive integers. You would have one integer twice.

While, possibly, one could somehow make the case that, with the wording "two positive integers," X and N could be the same, the truth is that, with the current wording, the case for saying that they must be different is too strong for the question to work.

So, the question has to be edited.

Try changing it to simply "If X and N are positive integers ..."

I bet that, with that wording, the percentage correct will increase substantially.
