If Assertion is CORRECT but Reason is INCORRECT. Explanation: Some oxoacids of phosphorus, like H3PO2 and H3PO3 contain P-H bonds, and they act as strong reducing agents. However, the P-H bonds are not ionisable and do not release H+ ions. Hence, the reason is incorrect, even though the assertion is correct.
