Answer:
The correct answer will be- sympathetic nervous system
Explanation:
The sympathetic nervous system is a part of the autonomic nervous system which is involved in controlling the autonomous functions of the body. The sympathetic nervous system controls the fight or flight response of the organism as it gets activated during these conditions.
