Which one of the following is an example of disproportionation reaction ?

A $3MnO_4^{2 - } + 4{H^ + } \to 2MnO_4^ - + Mn{O_2} + 2{H_2}O$
B $MnO_4^ - + 4{H^ + } + 4{e^ - } \to Mn{O_2} + 2{H_2}O$
C $10{I^ - } + 2MnO_4^ - + 16{H^ + } \to 2M{n^{2 + }} + 8{H_2}O + 5{I_2}$
D $8MnO_4^ - + 3{S_2}O_3^{2 - } + {H_2}O \to 8Mn{O_2} + 6SO_4^{2 - } + 2O{H^ - }$

Accepted Answer

MnO_4^{2 - }

is an intermediate oxidation state and is converted into compounds having higher and lower oxidation states.
