- A. to receive stimulus as sensory input.
- B. integration of stimulus with reaction.
- C. to trigger action as a motor response or motor output.
- D. All of the above.
Correct Answer: D

Motor output involves sending signals to muscles or glands to produce a response. Therefore, the nervous system's job encompasses all these functions, making 'All of the above' the correct answer.
