Solution

The correct option is D comproportionation
The reaction $M n O_{4}^{-} + M n^{2 +} \to M n O_{2}$ is an example of Comproportionation or Symproportionation.
It is a chemical reaction in which two reactants, containing same element in different oxidation state, will form a product in which the elements reach the same oxidation state.
