(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): \( \mathrm{NO}_{3}^{-} \)and \( \mathrm{PO}_{3}^{-} \)have similar formula types but differ structurally i.e. they have different types of hybridisation.
Reason (R): \( \mathrm{NO}_{3}^{-} \)ion exists as a free ion. On the other hand \( \mathrm{PO}_{3}^{-} \)exists as a cyclic or linear polymeric structure.
