Solution

Verified by Toppr

Correct option is D)

Since $E = \frac{- d V}{d r}$

A zero potential at a point never means that the electric field is also zero at a point always.
$E = 0$ when $V =$ constant.
If $V = 0$ ; then $E$ may or may not be zero.
Similarly, if $E = 0$ ; then $V$ must either be a constant or may be zero.
so correct option is(d).
