The question, along with OA, is flawed..

X and y are non negative integers so 0 or more..

1) \(y^x=1\)
Possible when x is 0 and y could be anything...so x^y will be 0..
Also when y is 1 and X can be anything... So x^y will be equal to x .
Insufficient

2) \((2^y)2^x=1=2^0.........y+x=0\)...
Not possible...
As both X and y are distinct so both cannot be 0 and none is negative, so no other combination will fit...
FLAWED
