Solution

The correct option is A Mn2++2ClO3MnO2+2ClO2
The unbalanced redox equation is as follows:
Mn2++ClO3MnO2+ClO2
All atoms other than H and O are balanced.
The oxidation number of Mn changes from 2 to 4. The change in the oxidation number is 2.
The oxidation number of Cl changes from 5 to 4. The change in he oxidation number is 1.
To balance the increase in the oxidation number with decrease in the oxidation number multiply ClO3 and ClO2 with 2.

Mn2++2ClO3MnO2+2ClO2
This is the balanced chemical equation.
