As we know that two equipotential surfaces can not intersect each other and lines of force are always perpendicular to the equipotential surface.
When two equipotential lines close together, the slope will be steep. So, close equipotential surfaces indicate a maximum electric field. $\left(E=-\frac{d V}{d x}\right)$
Ans: $(A),(C),(D)$ is correct ans
