Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R).\n Assertion (A): The orbital \( d_{z^2} \) has a doughnut-shaped ring along the xy-plane.\n Reason (R): The \( d_{z^2} \) orbital is unique and has its lobes oriented along the z-axis with a ring in the xy-plane. \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.
