V1=v2Conductor act as an equipotential surface so potential at A and B will be equal. This is one of the property of conductors. Thank you

Answer

The potential at the sphere will be because of the charge that is induced in it because of the charge placed outside it. Since, the sphere is an equipotential surface, the potential will be the same on all the points A, B and C. However, the sum of induced charges is zero and hence potential at the center is zero.
