Best answer
Right option is (a) It is also called phosphonic acid

The best I can explain: Hypophosphorous acid, also known as phosphinic acid, is an oxoacid of phosphorus in which, the oxidation state of phosphorus is +1. It is monobasic in nature, that is, it dissociates to produce one hydrogen ion. It is represented by the formula H3PO2.
