Easy data sufficiency question that's confusing. OG 12th ed

It does! Thank you! -
Is X an integer? 1. X/2 is an integer 2.2x is an integer. The answer is A. I'm confused because the book states that according to 1, X would be an even integer and so that should make it sufficient. But why would that be true if when X=1, X/2=1/2? Or am I approaching it the wrong way?
