D. `MnO_(3)`

Answer

C, D

Explanation

`overset(+6)(CrO_(3)` (Maximum oxidation state, cannot be oxidised further).
b. `overset(+3)(Al_(2))O_(3)`(Maximum oxidation state, cannot be oxidised further)
c. `overset(+4)(SO_(2))rarroverset(+6)(SO)_(4)^(2-)` (Can be oxidised further)
d. `overset(+6)(Mn)O_(3)rarroverset(+7)(Mn)O_(4)^(ө)` (Can be oxidised further).
