AIIMS 2018 Chemistry Normality and Molarity Assertion Reason Question

The assertion is true because the normality (N) of a 0.3 M solution of H₃PO₄ is indeed 0.6 N, as phosphoric acid (H₃PO₄) can donate three protons (H⁺), making its equivalent concentration twice the molarity. However, the reason is false because the equivalent weight of H₃PO₄ is actually $\frac{\text{Molecular weight of H₃PO₄}}{3}$, not H₃PO₃, which is a different compound (phosphorous acid). Options A and B are incorrect because they imply that the reason correctly explains the assertion, which it does not, and option D is incorrect as the assertion is true.
