My ans is B.

St 2 says WZ+XY is odd.
As we know, W/X and Y/Z are integers
hence, W/X +Y/Z is an integer
W/X +Y/Z=(WZ+XY)/XY,....
if St 2 is right then, W/X +Y/Z=(an odd no)/XY.
An odd no can only be divided by an odd no and will result in an odd no. That means XY is also odd and (WZ+XY)/XY is also an odd no.

St 1 gives many conditions, so nothing can be said using this statement.
