The correct sequence for the flow of information in a spinal reflex arc starts with sensory receptors detecting a stimulus. The information then travels via sensory axons to the spinal cord, where it is relayed through an interneuron. The interneuron connects to a motor neuron, which sends the signal through its axons to the effector (muscle or gland) to produce a response. This is accurately represented in option D.
