Which of the following is NOT a stage of Hans Selye's general adaptation syndrome?

• A. Alarm stage
• B. Resistance stage
• C. Exhaustion
• D. Homeostasis

Answer: (D)

The main idea is understanding the stages in Hans Selye’s general adaptation syndrome and recognizing what doesn’t belong in that sequence. In GAS, the body goes through three phases in response to stress: alarm, where fight-or-flight arousal kicks in; resistance, where the body attempts to cope and continues to adapt to the stress with ongoing hormonal activity; and exhaustion, where resources become depleted and vulnerability increases. Homeostasis, on the other hand, is the normal balanced state the body strives to maintain, not a stage during the stress response. So Homeostasis is not a stage of GAS.
