Clarification required

[psondh7610]

I need a clarification on this particular question -

If , sqrtxy = xy what is the value of x + y?

(1) x = -1/2
(2) y is not equal to zero

Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient.

Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient.

Both statements TOGETHER are sufficient, but NEITHER one ALONE is sufficient.

EACH statement ALONE is sufficient.

Statements (1) and (2) TOGETHER are NOT sufficient.

The answer to the question per the test guide is C.

But i fail to understand as to why the answer A is wrong?

As per the first statement x=-1/2. Now if i input the value of x in the equation sqrtxy = xy, then i can find the value of y and hence the value of x+y. So why is the answer to the problem C?
