Rancidity is mainly caused by what?

Answer and explanation

Correct answer: Oxidation of oils and fats

Rancidity is the spoilage of food containing oils or fats when these substances react with oxygen from the air. This oxidation produces unpleasant smells and tastes, so option A is correct. Freezing water, dissolving salt, and melting sugar are physical changes; none explains the characteristic oxidation and bad odour associated with rancid food.
