```										Dear Arnab Das      ,  f(x)=x^2/|x| f(x)= x   when x>o      = -x  when x<0          = 0   when x=0
so the function is continous for all x  and the function is not differentiabele at x =0   so the answer b is the right one  Please feel free to post as many doubts on our discussion forum as you can.
