1. x-y>-2
=> x>y-2
For y=1 we get x=-1 thus xy<0
For y=3 we get x=1 thus xy>0
Insufficient
2. x-2y<-6
=> x<2y-6
For y=1 we get x=-4 thus xy<0
For y=4 we get x=2 thus xy>0
Insufficient
Combining 1 and 2 gives
x>y-2 and x<2y-6
For y=1 we get -1<x and x<-4 thus for -ve value of x, xy<0
For y=4 we get x>2 and x<2 thus for +ve value of x, xy>0
Hence the solution is E.
Please correct me if i am wrong!
Thank you.
