Nuu. It's B

Be extra careful with inequality of unknown.
Because if these unknowns are negative, you gotta flip the direction of '>' accordingly. But if they are positive, you don't have to.

Always consider the possibility of the unknown being positive AND negative.

x/y > 1
could be
1)-10/-1 > 1 OR
2) 10/1 > 1

So, we are not sure which is the case

1. x/(3y) > 1/3
2 -x + p < -y + p

x/3y>1/3 ie : 3y/x<3 thus either y/x is +ve or -ve fraction and x>y or both x, y -ve and x< or >y....insuff

from two
-x<-y thus x>y sufff

my answer is B
