Question

We keep food at low temperatures in a refrigerator because it :

• A. saves money
• B. makes food more tastier
• C. kills bacteria present in the food
• D. is fashionable to keep the food in the refrigerator

Answer 1

The correct option is C kills bacteria present in the food

We keep food at low temperatures in a refrigerator because it kills bacteria present in the food. Microorganisms grow rapidly at room temperature, whereas their growth, enzymatic actions, and oxidative processes slow down under low temperatures, thereby reducing the risk of food poisoning.
