The correct answers are:
the electric field is zero
,
there can be no charge inside the region
As we know, the relation between electric field intensity E and electric potential $V$ is $E=\frac{-d V}{d r}$ as $E=0$ and for $V=$ constant. $\frac{\mathrm{dV}}{\mathrm{dr}}=0$
Thus electric field intensity $\mathrm{E}=0$.
