The correct answer would be A. somatic nervous system.
A somatic nervous system is sub-set of the peripheral nervous system which controls the voluntary actions and body movements with the help of skeletal muscles.
This system mainly consists of two types of nerves:
Afferent nerves: Theses are sensory nerves which carry stimulus or information from receptors to the central nervous system (brain and spinal cord).
Efferent nerves: These are also termed as motor nerves which carry commands or responsive information from the central nervous system to the muscles.
The muscles contract and produce movements.

A prey is an animal that is being eaten by a predator.
- If prey population decreases in number, the predator population will also decrease because there is not enough food for predators to survive.
- If predator population decreases, the prey population will increase because less prey will be eaten by predators.
- If prey population increases, the predator population could also increase because there will be a lot of food for them.
- If predator population increases, the prey population must decrease because more predators will eat more prey.
