D???

1- -2<x^2 , x^2 is always >0, sufficient.
2 - x^2>2x is true for x>2 so x^2>2x. Since y>0 then -3y<0 is true
Therefore 2x-3y will always be less than x^2, sufficient.

From I) -2<x^2
Squares are always +ve, thus we know that is true.Suff
From II) x>2 and we know for x>2, 2x<x^2
thus 2x-3y will always be lass than x^2. Suff

D.
