The correct sequence of a reflex arc is receptor, sensory neuron, interneuron, motor neuron, and effector. This sequence begins with the receptor, which detects a stimulus, followed by the sensory neuron, which transmits the information to the interneuron in the spinal cord. The interneuron processes the information and relays it to the motor neuron, which activates the effector (muscle or gland) to produce a specific response. Therefore, option D is the correct sequence.
