Oh such a confusion i have created for applying much shortcuts.
a^2-b^2= (a+b)(a-b)
and i applied for
(a+b)^2
I think i have to take some rest. Exam pressure force me to do this type of 3rd quality of mistakes.

Thanks bunuel.
You are great seriously.
1 kudos for you.

Dear Bunnel

,I solved this sum as follows

I assumed x/y as a.Therefore a+1/a>2 which becomes (a-1)^2>0.which implies a>1 therefore x/y>1.

a)In Option a since x not equal to y.either x can be greater or y can be greater therefore not sufficient.

b)x and y can have any number therefore not sufficient.

Due to this i choose option E.What mistake am I making
