Final answer:
Individuals who frequently experience general adaptation syndrome have an increased long-term risk of physiological and psychological damage due to the body's response to prolonged or repeated stress. They do not become immune to its effects.
Step-by-step explanation:
People who frequently experience the general adaptation syndrome (GAS) face a three-stage process: the alarm reaction, stage of resistance, and stage of exhaustion. This process involves the body's physiological reaction to stress, and while it can be adaptive and vital for survival in short-term, acute stress situations, it can lead to detrimental health effects if the stress is prolonged or repeated. Individuals who are exposed to GAS frequently do not become immune to its effects; rather, they have an increased risk of physiological and psychological damage in the long term. Conditions such as hypertension and coronary artery disease have been linked to prolonged or repeated stress. Therefore, the correct answer is (a) Have an increased risk of physiological and psychological damage.
