Solution
The correct option is C During exercise the parasympathetic control decreases
Both sympathetic and parasympathetic are mutually helpful during exercise. Our heart rate both at rest and during exercise is controlled by the nervous system. The sympathetic system increases our heartbeat during exercise. The parasympathetic system decreases our heart rate after exercise. As the pressure receptor send the signal to the vagus nerve of the parasympathetic system which then sends message to the medulla oblongata that slows down the heart rate. Thus the correct answer is option C.
