Solution

The correct option is D
All of the above

The n-factor of $K M n O_{4}$ varies depending on the type of solution where the reaction takes place and we calculate it based on change in oxidation state.

$(i) I n a c i d i c m e d i u m : (+ 7) (+ 2) K M n O_{4} ⟶ M n^{+ 2} V a l e n c e f a c t o r = 5 (i i) I n b a s i c m e d i u m : + 7 + 2 (K M n O_{4}) ⟶ (M n^{+ 6}) V a l e n c e f a c t o r = 1 (i i i) N e u t r a l m e d i u m : (+ 7) (+ 2) K M n O_{4} ⟶ M n^{+ 4} V a l e n c e f a c t o r = 3$
