The simple spinal reflex arc begins with a receptor, such as a sensory receptor in the skin, which detects a stimulus. The stimulus then travels along the afferent neuron to the integration center, which is typically a group of neurons in the spinal cord that processes the information. The information is then sent along the efferent neuron to the effector, which is usually a muscle or gland, causing a response. In this reflex arc, the order is receptor - afferent neuron - integration center - efferent neuron - effector, which is represented in choice A.
