Solution

The correct option is B Increase heart rate, relaxes bronchi
The sympathetic neural system orchestrates the fight-or-flight response. It increases muscle blood flow and tension, dilates pupils, accelerates heart rate and respiration, and increases perspiration and arterial blood pressure.
Where as, the parasympathetic neural system is responsible for stimulation of "rest-and-digest" or "feed and breed" activities that occur when the body is at rest, especially after eating, including sexual arousal, salivation, lacrimation (tears), urination, digestion, and defecation.
