A. Insects must occasionally shed their exoskeleton to grow a new one

Answer: A. Insects must occasionally shed their exoskeleton to grow a new one.

Explanation:

In the development process of insects from egg to adult form several intermediate stages occurs. In all immature insects the process of shedding of the skin and the exoskeleton takes place as the insect grows. The exoskeleton of the insect body does not expand as the insect grows it has to get shed and it get replaced with a new and large size exoskeleton. This allows the proper growth of the insect.
