Discussion

Explanation:

It can be very easy to figure out that (x + y) will always be greater than xy, only if one of them is 1. For eg. If x = 1 and y =2, then (x + y) = 3 and xy = 2.
Hence, (x + y) > xy.
Other than this, for all other values of x & y, (x + y) will always be less than xy, and hence, the ratio of $\frac{(x+y)}{xy}<1,$ and hence, cannot be an integer. Also, even if one of the values is 1, $\frac{(x+y)}{xy}$ will never be an integer. Hence, the answer is (a).
