(B) The chemical formula of phosphonic acid (also known as phosphorous acid) is $H_3PO_3$. In its structure,there are two $P-OH$ bonds and one $P-H$ bond. The hydrogen atoms attached to oxygen atoms are ionizable,whereas the hydrogen atom attached directly to the phosphorus atom is not ionizable. Since there are two $P-OH$ groups,it can release two $H^+$ ions in an aqueous solution. Therefore,phosphonic acid is dibasic.

Phosphonic acid $(H_3PO_3)$ is:
