In which action does the body respond before conscious thinking?
Answer and explanation
Correct answer: Reflex action
A reflex action is a rapid, automatic response to a stimulus that protects the body before deliberate conscious thinking is completed. For example, touching a hot object can cause the hand to withdraw through a reflex arc involving sensory neurons, the spinal cord and motor neurons. Thus option B is correct. Digestion, respiration and growth are important physiological processes, but they do not describe this immediate protective response.
