If X and Y are positive integers, X - 5 is divisible by 4 and Y - 1 is divisible by 4, all of the following could be the value of X - Y Except?	Pick one:
A) 0
B) 8
C) 4
D) 7
E) 24
X-5 = 4Y   =&gt; P = 4Y + 5 = 5,9,13,17,21,25,29,33,37,41,45   Y-1 = 4X   =&gt; Y = 4X + 1 = 1,5,9,13,17,21,25,29,33,37,41   0=5-5   8=13-5   4=5-1   24=45-21   So , we can see that all the answer choices are possible here except 7
