Which statement correctly matches a stress type with its description?

• A. Acute stress is the body's immediate reaction to a perceived threat.
• B. Fatigue is the body's immediate reaction to a perceived threat.
• C. Psychological stress is the body's immediate reaction to a perceived threat.
• D. Chronic stress is the body's immediate reaction to a perceived threat.

Answer: (A)

The main idea here is understanding how stress types differ by how long they last and how the body responds. Acute stress is the body's immediate reaction to a perceived threat, kicking in the fight-or-flight response with quick, short-lived physiological changes to help you act quickly. That direct link—immediate threat triggers rapid bodily response—is why this statement fits best. Fatigue isn’t a stress type; it’s a state of tiredness that can come from many factors and doesn’t describe the body’s initial response to danger. Psychological stress refers to the mental and emotional strain from challenging situations, not the body's immediate physical reaction to a threat. Chronic stress describes ongoing, long-term stress, not the quick onset that occurs right after a threat is perceived.
