Solution

The correct option is C Increase heart beat
The sympathetic nervous system deals with the response to stress and danger, releasing epinephrines (adrenaline), and in general, increasing activity and metabolic rate. So, due to sympathetic stimulation, heart rate increases, to provide body more and more oxygen and nutrients.
