Pulling the hand back after touching a hot object is an example of what?
Answer and explanation
Correct answer: Reflex action
Touching a hot object stimulates pain and temperature receptors in the skin. The sensory impulse travels through a sensory neuron to the spinal cord, where a rapid response pathway activates muscles to withdraw the hand before conscious awareness is complete. This automatic protective response is a reflex action. Therefore option A is correct; voluntary, growth, and hormonal actions do not describe this immediate withdrawal.
