Two Charged Metal Spheres Are Connected by a Wire

Two charged metal spheres are connected by a wire. Sphere A is larger than sphere B, as shown. The magnitude of the electric potential of sphere A

A) is greater than that at the surface of sphere B.
B) is less than that at the surface of sphere B.
C) is the same as that at the surface of sphere B.
D) could be greater than or less than that at the surface of sphere B, depending on the radii of the spheres.
E) could be greater than or less than that at the surface of sphere B, depending on the charges on the spheres.
