___________ is the process of complete or incomplete oxidation or hydrolysis of fats and oils when exposed to air, light, moisture, or bacterial action that spoils food.

Correct option is A

The correct answer is (a) Rancidification
· The process of complete or incomplete oxidation or hydrolysis of fats and oils when exposed to air, light, moisture, or bacterial action that spoils food is called Rancidification.
· Hydrogenation: This is a chemical process where hydrogen is added to unsaturated fats to make them saturated. This process increases the shelf life of fats and oils but also increases their trans-fat content, which is considered unhealthy.
· Auto-oxidation: This is a specific type of oxidation that occurs spontaneously in certain molecules, including some fats and oils. While it plays a role in rancidification, it's not the specific process itself.
· Auto reduction: This is the opposite of auto-oxidation, where a molecule gains electrons and reduces its oxidation state.
