IMO C.. yes y = 2..
from 2 y=1 or 2
by taking both the statements together..
y=2..
hence C.

I say C also: Both.

You need #1 to discount y=1 and you need #2 to not go any further.

you'll need both...if X is multiple of y, and X+2 is also a multiple, so 2 is a multiple of y, so y could be either 1 or 2, if y != 1, then y has to be 2
