Since points A and B lie on the same equipotential surface, the potential difference between them is zero. Work done in moving a charge across an equipotential surface is given by:
W = qΔV
Since ΔV = 0, the work done is zero.
Thus, the correct answer is (d) Zero.

    1. The correct answer is (d) Zero.
      On an equipotential surface, all points have the same electric potential. Since work done (W = qΔV) depends on the potential difference (ΔV) and ΔV = 0 on an equipotential surface, no work is required to move an electron between points.
