Final answer:
The correct answer is 'b) Autonomic' since the parasympathetic and sympathetic nervous systems are part of the autonomic nervous system, which itself is a subdivision of the peripheral nervous system.
Step-by-step explanation:
The parasympathetic and sympathetic nervous systems are both part of the autonomic nervous system, which is a subdivision of the peripheral nervous system. The autonomic nervous system regulates involuntary functions of our internal organs and glands, and operates autonomously, meaning it acts without conscious control. The sympathetic nervous system prepares the body for stress-related activities, often referred to as the "fight-or-flight" response, while the parasympathetic nervous system supports body functions during rest and recovery, controlling processes like digestion and promoting a relaxed state. Therefore, the correct answer to the question is 'b) Autonomic'.
