Options
A Perpendicular
Correct Answer
B At 45 degrees
C Antiparallel
D Parallel
Correct Answer

Option A is the correct answer.

Detailed Explanation

Field lines are always PERPENDICULAR (normal) to equipotential surfaces. Reason: no work is done moving a charge along an equipotential, so E can have no component along that surface.

Hint

Field lines are always PERPENDICULAR (normal) to equipotential surfaces.
