A) The potential is lowest, but not zero, at the center of the sphere.
B) The potential at the center of the sphere is zero.
C) The potential at the center of the sphere is the same as the potential at the surface.
D) The potential at the surface is higher than the potential at the center.
E) The potential at the center is the same as the potential at infinity.
