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 involves five main components: receptor, sensory neuron, integration center, motor neuron, and effector.

Step 2: Identify the role of each component in the reflex arc. The receptor detects the stimulus, the sensory neuron transmits the signal to the integration center, the integration center processes the information, the motor neuron carries the response signal, and the effector performs the action.

Step 3: Analyze the order of the components in the reflex arc. The correct sequence is: Receptor → Sensory neuron → Integration center → Motor neuron → Effector. This order ensures the stimulus is detected, processed, and responded to appropriately.

Step 4: Compare the given options to the correct sequence. Evaluate each option to determine if it matches the correct order of components in the reflex arc.

Step 5: Select the option that matches the correct sequence. The correct answer is the one that lists the components in the order: Receptor → Sensory neuron → Integration center → Motor neuron → Effector.
