Explanation Reason for correct answer: Option a. is given as “sympathetic.” The autonomic nervous system controls involuntary muscles and glands. The sympathetic nervous system is a subdivision of the autonomic nervous system. Sympathetic neurons are activated during stress and danger. Signals from the sympathetic neurons increase the heart rate, blood pressure, and breath rate during stress, excitement, and danger. These neurons release norepinephrine at the synapse with target organs...
