Answer

Brief Explanations:

In electrostatics, electric - field lines are always perpendicular to equipotential lines. This is because the work done in moving a charge along an equipotential surface is zero. If the field line was not perpendicular to the equipotential line, there would be a component of the electric field along the equipotential line, which would mean work is done in moving a charge along it, contradicting the definition of an equipotential surface. Electric - field lines are not always parallel to each other (as in non - uniform fields), they do not cross each other (as that would imply two directions of the electric field at a point), and they are not always perpendicular to each other.

Answer:

B. Field lines should always be perpendicular to the equipotential lines.
