Text Solution

Verified by Experts

The correct Answer is:
B
Cooling food, stops microbes from growing and reproducing, and hence preserves food. A refrigerator keeps food at about `5^(@)C` and prevent it from spoiling for a few days. A deep freezer preserves food at below -`18^(@)C` and can prevent it from getting spoilt for a few months. However, once the food is taken out of the freezer and warmed, microbes start growing again.
