O₃ cannot oxidise:

A.KI

B.FeSO₄

C.KMnO₄✓ Correct

D.K₂MnO₄

Explanation

In the oxidation process, electrons are lost. The Mn in 4 KMnO has the maximum oxidation state which is +7. So, it cannot undergo any further oxidation as it cannot lose any more electrons. Hence, 4 KMnO cannot be oxidized by 3 O .
