Solution

The correct option is C

1, 3, 4, 5


This has to be answered based on the oxidation number of the central metal atom in each case.
To start with Mn has +7 oxidation number in KMnO4. Likewise, we have
+6MnO24
+4MnO2
+3Mn2O3
+2Mn2+

The number of electrons transferred in each case is 1, 3, 4, 5 respectively.
