Which part of Mirna's nervous system was activated while she was sitting on the couch and telling the story to her roommate

A) Her sympathetic nervous system
B) Her parasympathetic nervous system
C) Her afferent nervous system
D) Her efferent nervous system

The parasympathetic nervous system is responsible for bringing the body back to its rest and digest state after a perceived threat. In this case, after the dog incident, Mirna's sympathetic nervous system would have been activated causing her heart rate to increase and her breathing to become more erratic to prepare her body for fight or flight. Once the threat was removed, the parasympathetic nervous system would have taken over, bringing her body back to its normal state. Therefore, while she was sitting on the couch and telling the story to her roommate, her parasympathetic nervous system would have been active.
