(1) If both Assertion (A) and Reason (R) are True and the Reason (R) is a correct explanation of the Assertion (A).
(2) If both Assertion (A) and Reason (R) are True but Reason (R) is not a correct explanation of the Assertion (A).
(3) If Assertion (A) is True but the Reason (R) is False.
(4) Assertion (A) is False but Reason (R) is True.
Assertion (A): Electron affinity values of the \( 3^{\text {rd }} \)-period elements on the extreme right of the periodic table except noble gases are generally more than the \( 2^{\text {nd }} \)-period element of the same group.
Reason (R): Due to the smaller atomic size of the \( 2^{\text {nd }} \)-period element, its electron density increases which oppose the addition of an electron.
