Option 2: at its low temperature, the germs are killed
Option 3: at its low temperature, the germs are frozen
Option 4: it sterilizes the food
Correct Answer: at its low temperature bacteria and moulds are inactive
Solution : The correct option is at its low temperature bacteria and moulds are inactive.
Refrigerators aid in the preservation of food by keeping it at a low temperature, which prevents the development and activity of bacteria, moulds, and other microbes that cause food to deteriorate. The freezing temperature slows down these bacteria' enzymatic and metabolic activities, reducing their capacity to multiply and break down food. Refrigeration helps to increase the shelf life of perishable foods by producing an environment in which bacteria and moulds are less likely to develop and cause foodborne diseases.
