IS |X-Y| > |X| - |Y| ?
a) Y<X
b) XY<0

Statement A:
If, Y=-1 X=1 then LHS=2 and RHS=0 -->Correct
If, Y=1 X=3 then LHS=2 and RHS=2 -->Incorrect
Thus INSUFFICIENT

Statement B:
Either of X or Y is -ve.
If, Y=-1 X=1 then LHS=2 and RHS=0 -->Correct
If, Y=1 X=-3 then LHS=4 and RHS=2 -->Correct
Thus SUFFICIENT

Thank you for the explanation

Yes OA is B.

And i was making some calculation mistake during exam and was not able to figure out the root cause.

Guess i have to use pen and paper to get rid of such mistakes.
