Hi Vasudha.. :)

i completely agree with your claim.
Basically, my point was if i could find a function which satisfies the given condition then, i can rule out options using that.
(Sorry, earlier i wrote " that would be the answer" )

Like if f(x)= x-1
then option A is ruled out.

if f(x)= sinx
then option C is ruled out.

Now, Only options left are B and D.
