He does not act in any obviously unusual ways nor possess strange beliefs about the world. Of the following Personality Disorders, Theo appears to be:

C. Antisocial

D. Schizotypal

Theo appears to be A. schizoid.

Explanation:

People with schizoid personality disorder display indifference for social relationships as well as a limited range of emotions. They commonly avoid closeness, preferring to be alone and do activities that do not require the presence and help of others. They show little change in their moods, most of the time showing coldness and detachment. They are also indifferent to criticism or praise, and are close only with their relatives. There are no signs, however, of possessing strange beliefs and views of the world. As we can see, the description of Theo fits the symptoms of schizoid disorder.
