Suppose limh->0 (f(h)-f(0))/h =+infinity and f(0)=0. What kind of feature can best explain this?

a)such scenario is not possible
b)f(x) has a vertical tangent at x=0
c)f(x) must be discontinuous at x=0
d)f(x) has a vertical assymptote at x=0, and f(0) is defined to be 0.
 
I tried a) and b) but they are not correct.
 
what is the right answer?

I thought it couldn't be D because there can't be a point on an asymptote.
