0(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): \( \mathrm{Na}^{+} \)and \( \mathrm{Al}^{3+} \) are isoelectronic but the magnitude of ionic radius of \( \mathrm{Al}^{3+} \) is less than that of \( \mathrm{Na}^{+} \).
Reason (R): The magnitude of the effective nuclear charge on the outermost shell electrons in \( \mathrm{Al}^{3+} \) is greater than that in \( \mathrm{Na}^{+} \).
