Solution

The correct option is B MnO2
For equivalent weight of MnSO4 to be half of its molecular weight, change in oxidation state must be equal to +2. It is possible only when oxidation state of Mn in product is +4. Since oxidation state of Mn in MnSO4 is +2
In MnO2 Oxidation state of Mn=+4
Change in Oxidation state of Mn=+4(+2)=+2
