What is the process called when oils and fats develop an unpleasant smell on exposure to air?

Answer and explanation

Correct answer: Rancidity

Oils and fats slowly undergo oxidation when exposed to oxygen in air, producing an unpleasant smell and taste. This process is called rancidity. Corrosion is the deterioration of metals due to environmental action, so it does not apply to oils and fats.
