Final answer:
The three stages of the General Adaptation Syndrome (GAS) are alarm reaction, stage of resistance, and stage of exhaustion, making the correct answer (D) Alarm, resistance, exhaustion.
Step-by-step explanation:
Hans Selye's General Adaptation Syndrome (GAS) model outlines the body's physiological response to stress through three distinct stages: alarm reaction, stage of resistance, and stage of exhaustion. The alarm reaction is the immediate response to a threat, often characterized by the fight-or-flight response facilitated by stress hormones like epinephrine and norepinephrine.
During the stage of resistance, the body adapts to the stressor and tries to cope, despite remaining on high alert. Eventually, if the stress continues, the body reaches the stage of exhaustion, where its resources are depleted, leading to potential health problems. The correct answer to the question is (D) Alarm, resistance, exhaustion.
