Answer 1

The Correct Option is B

The sympathetic nervous system mediates the fight or flight response by preparing the body for stress (increasing heart rate, redirecting blood flow, etc.). It is responsible for the body’s reaction to threats.

Parasympathetic system: Rest and digest (opposite of fight or flight).

Serotonergic & Histaminergic systems: Not directly related to fight or flight.
