Condition I

If f is defined at x=a, then,


\lim _(x\rightarrow a)f(x)=f(a)

The above is true but it is not true for a stepwise function

Condition II

If f is continuous at x=a, then


\lim _(x\rightarrow a)f(x)=f(a)

The second statement above is true for it meets the condition for continuity of a limiting function

Condition III

If f is differentiable at x=a, then


\lim _(x\rightarrow a)f(x)=f(a)

The third statement above is also true for a limiting function of differentiation.

Hence, statements II and III are true, OPTION D
