Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R).\n Assertion (A): The boundary surface diagram for an \( s \)-orbital is spherical in shape.\nReason (B): The probability of finding the electron at a given distance from the nucleus is equal in all directions for an \( s \)-orbital. \nIn the light of the above statements, choose the correct answer from the options given below:

1. Both (A) and (R) are true and (R) is the correct explanation of (A).
2. Both (A) and (R) are true but (R) is NOT the correct explanation of (A).
3. (A) is true but (R) is false.
4. (A) is false but (R) is true.
