I am not understanding the question....

Are you asking whether x^3 * y^4 = 2000 ?
given
St1 x is an integer
St2 y is an integer

If that is the case it is C...
x = 5, y = 2

I am taking back my answer. It should be E

St 1 say s that x is an integer
x = ...., -2, -1, 0, 1, ....

St 2 says that y is an integer
y = ...-2, -1, 0,1 ...
Combining 1 and 2 x and y can be any integers.
Only when x = 5 and y = 2, will the above condition hold.
Else not

Hence E.....
