Assertion (A) : Work done to move a change between two points is zero inside a uniformly changed shell.

Reason (R) : Potential inside a uniformly changed shell is constant and equal to the potential at its surface.

(1) Both (A) & (R) are correct, and Reason is the correct explanation of (A).

(2) Both (A) & (R) are correct but R is not correct explanation of A.

(3) A is correct and b is incorrect

(4) A is correct and R is correct
