(D) The chemical formula of ammonium phosphomolybdate is $(NH_4)_3[P(Mo_{12}O_{40})]$.In this complex,the phosphate ion is $PO_4^{3-}$ and the molybdate unit is $MoO_3$.Let the oxidation state of $Mo$ be $x$.In $MoO_3$,the oxidation state of oxygen is $-2$.$x + 3(-2) = 0$$x - 6 = 0$$x = +6$.Thus,the oxidation state of $Mo$ is $+6$.
