The sympathetic nervous system is responsible for the "fight or flight" response, which involves an elevated heart rate, increased respiration, and other physiological responses to stress. However, once Elena sees her son is safe, her body would likely activate the parasympathetic nervous system, which works to return the body to its pre-stress state. This includes slowing the heart rate, decreasing respiration, and promoting relaxation. Therefore, the best choice is A) parasympathetic.
