Answer:
The correct answer is "The nervous system transmits pain, while the endocrine system elicits the fight or flight response".
Explanation:
One of the roles of the nervous system is to transmit pain to alarm the body that something is going on and that it acts accordingly. The nerve pathway is the one that carries the message of pain from the affected area to the spinal cord and up to the brain. On the other hand, the endocrine system is the one that elicits the fight or flight response. During stressful conditions, the adrenal glands of the endocrine system release epinephrine and norepinephrine that acts during the fight or flight response.
