Answer: (C)

Verified step by step guidance

1. Step 1: Begin by understanding the autonomic nervous system (ANS), which is a part of the peripheral nervous system responsible for involuntary control of body functions such as heart rate, digestion, and respiratory rate.
2. Step 2: Learn that the autonomic nervous system is divided into two main branches: the sympathetic division and the parasympathetic division. These divisions work in opposition to maintain homeostasis.
3. Step 3: Understand the role of the sympathetic division, which is often referred to as the 'fight or flight' system. It prepares the body for stressful or emergency situations by increasing heart rate, dilating airways, and inhibiting digestion.
4. Step 4: Understand the role of the parasympathetic division, which is often referred to as the 'rest and digest' system. It promotes relaxation and recovery by slowing the heart rate, stimulating digestion, and conserving energy.
5. Step 5: Recognize that the other options provided in the question (e.g., somatic; sensory, central; peripheral, afferent; efferent) are incorrect because they refer to different aspects of the nervous system that are not specific to the autonomic nervous system's divisions.
