D. The General Adaptation Syndrome

Explanation:

Hans Selye, an endocrinologist, developed the "Stress Theory." He showed the relationship of "stress" to the person's development of disease.

Under stress, a person's body experiences changes. The person tries to cope with these through three stages: Alarm Reaction Stage, Resistance Stage and Exhaustion Stage. It is at the last stage that a person's immune system is placed at a huge risk. Once the person is exposed to a stressor for a period of time, he becomes hopeless and his body tends to give up coping. He then succumbs to stress-related illness.
