Best answer
The correct choice is (b) False

The best I can explain: The highest oxidation state in the oxides of any transition metal is equal to its group number, for example, 7 in Mn2O7. Beyond group 7, no higher oxides of iron above Fe2O3 are known. Some metals in higher oxidation state stabilize by forming oxocations.
