(B) The chemical formula is $Ba(H_2PO_2)_2$.Let the oxidation number of $P$ be $x$.The oxidation number of $Ba$ is $+2$,$H$ is $+1$,and $O$ is $-2$.Sum of oxidation numbers $= 0$.$2 + 2 	imes [2 	imes (+1) + x + 2 	imes (-2)] = 0$$2 + 2 	imes [2 + x - 4] = 0$$2 + 2 	imes [x - 2] = 0$$2 + 2x - 4 = 0$$2x - 2 = 0$$2x = 2$$x = +1$.
