has a lot on his plate. He works full-time, has a second part-time job, and is building a new consulting company based on his son's special needs. He has a lot of stress in his life but seems to be coping with everything quite well (for the moment, anyway). According to Hans Selye, he is in which stage of the general adaptation syndrome

the resistance stage

Explanation:

Hans Selye, who is a medical doctor and a researcher, is known to have developed the three stages the body undergoes to respond to stress, while describing the physiological changes that accompany each stage. This three-stage process is what he referred to as general adaptation syndrome.

The general adaptation syndrome three-stage process include the the alarm stage, the resistance stage, and the exhaustion stage.

The resistance stage is the second stage that after the initial alarm stage of shock caused by the stress. In this resistance stage, the individual gradually copes with stress as the "flight or fight" response begin to lessen and body function such as heart rate, blood pressure begins to normalize. Also, the body system begins to recover and repair itself as the individual copes.

From the information given in the question, we can infer that the individual is in the resistance stage of the general adaptation syndrome.
