The action is an illustration of a basic reaction because the brain is not involved. When a frog's leg is pinched, receptors on the skin pick up the input and create a sensory impulse. Through the dorsal sensory root of a spinal nerve, this impulse travels to the spinal cord. The sensory impulse is subsequently converted into a motor impulse by the spinal cord. The muscles in the legs then receive this stimulus. When the muscles receive the impulse, they tighten up, and the leg is pulled back to get away from the stimuli. So, "simple reflex" is the correct answer which is present in option 2..
