(C) The electric potential $V$ in an electric field $\vec{E}$ is related by the relation $dV = -\vec{E} \cdot d\vec{r}$.This implies that the electric potential decreases as we move in the direction of the electric field.In the given figure,the electric field $\vec{E}$ is directed towards the right.Point $B$ is the furthest to the left,followed by point $C$ (which is at the same vertical level as $B$ but slightly to the right),and point $A$ is the furthest to the right.Since the potential decreases in the direction of the electric field,the point furthest to the left will have the highest potential.Therefore,the electric potential is maximum at point $B$.

$A, B$ and $C$ are three points in a uniform electric field as shown in the figure. The electric potential is
