I get E.

1. x/y can be 1/2 or an integer, so insuff

2. Y is odd. That does not tell us anything. so Insuff.

Shouldn't it be C ?

If you combine both st_1 and st_2 x/y has to be an integer.

For example x/y = 1/2 will become an invalid case...

lets assume y = 7. For 2x/y to be an integer, one will be forced to pick values of x like 7,14,21,28...making x/y an integer.

No ?

For the same reason.
