Pulling the hand back immediately after touching a hot object is what type of action?
Answer and explanation
Correct answer: Reflex action
Touching a hot object produces a harmful stimulus detected by sensory receptors. The impulse travels through a reflex arc, and the spinal cord rapidly sends instructions to the muscles before conscious analysis by the brain is complete. This immediate, automatic protective response is called a reflex action, so option B is correct. A voluntary action requires conscious choice, while growth and digestion are unrelated physiological processes.
