(1) If both Assertion (A) and Reason (R) are True and the Reason \( (\mathrm{R}) \) 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): The atomic radii of the elements of the oxygen family are smaller than the atomic radii of the corresponding elements of the nitrogen family.
Reason (R): The members of the oxygen family are more electronegative and thus have lower values of nuclear charge than those of the nitrogen family.
