If xy>0 it means either x & y both are positive or both are negative.Statement 1: if x-y= 3, it means if x& y are positive then x should be greater than y.If x & y are negative then x should be less than y but we dont know values of x & y hence insufficient.
Statement 2 : x2 = 9 : x can be positive or negative hence insufficient.Together also they are insufficient.Hence Ans: D
