Which physiological stress reaction prepares individuals to confront or escape perceived threats?

• A. Omnipresence
• B. Acquired Immunodeficiency Syndrome
• C. Flight-or-Fight Response
• D. Blue Curtain

Answer: (C)

The flight-or-fight response is the body's rapid, automatic reaction to perceived threats. When danger is sensed, the brain triggers the sympathetic nervous system and a surge of stress hormones, which together prepare the body for quick action. Physiological changes occur quickly: heart rate and blood pressure rise, breathing speeds up, pupils dilate, muscles tense, energy stores are mobilized, and digestion slows. These adjustments increase strength and speed and sharpen focus, helping you confront the threat or escape from it. This response evolved to deal with acute stress and is seen across many species, making it the best description of a physiological reaction that prepares someone to face or flee danger. The other terms don’t describe this kind of bodily preparation for threat—they don’t refer to a stress-response mechanism.
