Autonomic nervous system</h2>
Explanation:
The autonomic nervous system is the nervous system which is considered a part of the peripheral nervous system. The autonomic nervous system is divided into two systems- parasympathetic and sympathetic nervous system.
The sympathetic nervous system gets activated in the dangerous situation where it produces energy to respond either to fight or to flight.
The parasympathetic system gets activated after the sympathetic system and is antagonistic to the fight or flight responses that produce chemicals for the mind to relax.
Thus, Autonomic nervous system is the correct answer.
