Verified step by step guidance

Step 1: Understand the concept of a reflex arc. A reflex arc is the neural pathway that controls a reflex action. It typically involves five main components: receptor, sensory neuron, integration center, motor neuron, and effector.

Step 2: Identify the role of the integration center in the reflex arc. The integration center is located within the central nervous system (CNS) and is responsible for processing the sensory input and generating a motor response.

Step 3: Review the typical diagram of a reflex arc. In such diagrams, Roman numerals are often used to label the components. The integration center is usually represented by a specific numeral, which corresponds to the CNS.

Step 4: Compare the given Roman numerals (I, II, III, IV) to the standard labeling conventions in reflex arc diagrams. The numeral that most commonly represents the CNS integration center is III.

Step 5: Confirm the correct answer based on the question and your understanding of reflex arc diagrams. The numeral III is indeed the correct representation of the CNS integration center in this context.
