We have to consider two cases
1) if x is positive no matter what is the value of y, the result will be positive
2) if y is even no matter what is the value of x, the result will be positive
1 stm --> x is positive. Suff
2 stm --> y is negative. insuff
IMO

Is \(x^{–y}\) positive?
(1) x is positive.
(2) y is negative.
(1) x is positive.
(2) y is negative.
\(x^{–y}\) positive
#1
x +ve ; then y whether + or -ve will not make difference
sufficient as value will be +ve only
#2
y is -ve ; then value of x should be +ve as well , else its insufficient when x=-ve ;
x is not know in this cases
IMO A
