Potassium Permanganate is used for purifying drinking water

Potassium permanganate is a point-of-entry treatment method that oxidizes dissolved iron, manganese, and hydrogen sulfide into solid particles that are filtered out of the water. It can also be used to control iron bacteria growth in wells.

que-Potassium Permanganate is used for purifying drinking water, because

opt1- It is a sterilising agent.

opt2-It dissolves the impurities of water.

opt3-It is a reducing agent.

opt4-It is an oxidising agent.

option-4 is right

Potassium permanganate (KMnO4) oxidizes dissolved iron, manganese, and hydrogen sulfide into solid particles that are filtered out of the water.
