Solution

## The correct option is C 1, 3, 4, 5The oxidation number of Mn in KMnO4, MnO2−4,MnO2,Mn2O3 and Mn2+ is 7, 6, 4, 3 and 2 respectively. The number of electrons transferred corresponds to the change in the oxidation number. So, when KMnO4 acts as an oxidising agent and ultimately forms MnO2−4,MnO2,Mn2O3 and Mn+2, then the number of electrons transferred in each case are: 7-6=1, 7-4= 3, 7-3= 4, 7-2= 5 respectively. Hence, (c) is the correct answer.
