what if x*/y/ is zero then both x and Y will be zero

(1) INSUFFICIENT: Since x2 is positive whether x is negative or positive, we can only determine that x is not equal to zero; x could be either positive or negative.
(2) INSUFFICIENT: By telling us that the expression x × |y| is not a positive number, we know that it must either be negative or zero. If the expression is negative, x must be negative (|y| is never negative). However if the expression is zero, x or y could be zero.
(1) AND (2) INSUFFICIENT: We know from statement 1 that x cannot be zero, however, there are still two possibilites for x: x could be positive (y is zero), or x could be negative (y is anything).
The correct answer is E.
