Figure- shows three spherical shells is separate situations, with each shell having the same uniformly distributed positive charge. Points I, 4 and 7 are at the same radial distances from the centre of the their respective shells so are points 2, 5 and 8 and so are points 3, 6 and 9. With the electric i:otential taken equal to zero at an in finite distance, which of the following statements is/are correct:

A

Point 3 has highest potential

B

Point l, 4 and 7 are at same potential

C

Point 8 has lowest potential

D

Point 5 and 8 are at same potential
