Answer:

4. The kinetics for the enzymatic processes of microorganisms responsible for decomposition are slowed.

Explanation:

Generally  most enzymes work best at optimum temperature of 35-40 degree centigrade, This is because enzymes are proteins, and  proteins are sensitive to temperature.

Therefore at low temperature of refrigeration below -18 degree, enzymatic processes of microorganisms need for biochemical activities, oxidative activities and   growth are  slowdown(thus  microorganism population is reduced) . Microorganisms are inactive. Therefore the rate of food decomposition is slowed down,which  prolonged  nutritional value of the food.
