Solution

The correct option is A An oxidising agent
Potassium permanganate is used in organic chemistry in the form of an alkaline or neutral solution. It is a salt containing $K^{+}$ and ${M n O_{4}}^{-}$ ions. Oxidation involves the gain of oxygen and an oxidizing agent is a chemical that oxidizes something else. The permanganate in potassium permanganate has the anion ${M n O 4}^{-}$ that is the reason for its strong oxidizing properties.
