(C) The compound is $Ba(H_2PO_2)_2$. The barium ion is $Ba^{2+}$,so the hypophosphite ion is $H_2PO_2^-$.Let the oxidation state of $P$ be $x$.In the ion $H_2PO_2^-$,the sum of oxidation states equals the charge on the ion:$(2 	imes (+1)) + x + (2 	imes (-2)) = -1$$2 + x - 4 = -1$$x - 2 = -1$$x = +1$Therefore,the oxidation state of phosphorus is $+1$.
