Best answer
The correct option is (c) ethylene

The best explanation: Potassium permanganate acts as ethylene scavenging system. It is the most common agent of ethylene removal, which oxidizes ethylene to acetate and ethanol. Ethylene is a natural plant hormone produced by ripening produce. It accelerates respiration, resulting in maturity and senescence. Removing ethylene from a package environment helps extend the shelf life of fresh produce.
