  • D Zero ✔ ✖
Correct Answer

Explanation

Since the charge is located on an equipotential surface, all points on the surface have the same electric potential. Therefore, no work is required to move the charge along the equipotential surface since the potential remains constant. The work done is given by the product of the displacement, charge, and electric field intensity, but in this case, it is zero.
