Here are the essential concepts you must grasp in order to answer the question correctly.
Visceral Reflex Arc
A visceral reflex arc is a neural pathway that mediates involuntary responses to stimuli affecting internal organs. It typically involves sensory neurons that detect changes in the internal environment, interneurons that process the information, and motor neurons that trigger a response in the effector organs, such as smooth muscle or glands.

Components of the Reflex Arc
The components of a reflex arc include the sensory receptor, sensory neuron, integration center (often within the spinal cord), motor neuron, and effector. The sensory receptor detects a stimulus, the sensory neuron transmits the signal to the integration center, which processes the information and sends a command via the motor neuron to the effector, resulting in a response.

Autonomic Nervous System
The autonomic nervous system (ANS) regulates involuntary bodily functions and is divided into the sympathetic and parasympathetic systems. The visceral reflex arc is primarily governed by the ANS, which controls reflexes related to internal organs, such as heart rate, digestion, and respiratory rate, ensuring homeostasis in response to various stimuli.
