The electrostatic potential on the surface of a charged conducting

The electrostatic potential on the surface of a charged conducting sphere is 100V. Two statements are made in this regard:

S1: At any point inside the sphere, the electric intensity is zero

S2: At any point inside the sphere, the electrostatic potential is 100V

Which of the following is a correct statement?

(a) S1 is true but S2 is false

(b) Both S1 and S2 are false

(c) S1 is true, S2 is also true, and S1 is the cause of S2

(d) S1 is true, S2 is also true but the statements are independent
