The hunted deer is experiencing a fight-or-flight response and is attempting to escape the danger posed by the approaching hunters. This response is controlled by the sympathetic nervous system, which activates in response to stress and triggers physiological changes that prepare the body for either fighting or running away. The parasympathetic nervous system, on the other hand, is responsible for rest and digestion and would not be active in this situation. Therefore, Option A is the correct choice.
