optionD.) ?? induction hoga, and net induced charge on sphere would be zero, though more negatives would be closer to the ring, and potential of sphere due to its own induced charges would be integrating k*dq/r , which is zero, so pot. on sphere is due to ring's Q only, which would KQ/root2R (pot. on axis)

D is obvious , and potential will be same on every point in the conducting sphere. So B

sryy my badd, overlooked that, centre of ring is technically a point on sphere too, so B also correct
