Answer: Option B

Explanation: Radioisotopes can be used to preserve food. This process increases the shelf life of food by  killing the bacteria, fungi and parasites found in the macromolecules.

The food gets spoiled because of the bacteria present in the food that leads to food spoilage.

With the help of radioisotopes, the bacteria causing spoilage can be killed and  removed and the shelf life of food increases.
