Solution

The correct option is A 1. (A) p,s (B) p,s (C) q,r (D) r,s
(A) Hypo phosphoric acid (H4P2O6) has sp3 hybridization. In this molecule all hydrogens are ionizable in water.
Image result for hypophosphoric acid

(B) Pyro phosphoric acid (H4P2O7) has sp3 hybridization. In this molecule all hydrogens are ionizable in water.
Image result for pyrophosphoric acid

(C) Boric acid (H3BO3) is a Lewis acid and monobasic in water.
Structural formula

(D) Hypo phosphorus acid (H3PO2) has sp3 hybridisation and is monobasic in water.
Image result for hypophosphorous acid


So answer is A.
