Gary spends much of his day wondering "what if" about catastrophic scenarios. This thought process makes him feel he has control over the situation. However, the lack of any catastrophes only reinforces the "what if?" behavior. Gary would most likely be diagnosed with: (A) Obsessive compulsive disorder. (B) Major depression (C) Generalized anxiety disorder (D) Social anxiety disorder

The correct answer is C. Generalized anxiety disorder

Explanation:

In psychology, the general anxiety disorder is a type of disorder in which the individual shows an excessive worry or anxiety that is persistent about different issues such as family, job or future. This is classified as a disorder because the individual is unable to control his anxiety and because of this, it ic common individuals with this disorder have persistent thoughts about the situation or issue that causes anxiety. This differs from obsessive-compulsive disorder because this focuses on persistent and repetitive behaviors, from major depression because this involves persistent sadness and from social anxiety disorder because in this anxiety is triggered by social situations.

Considering this, Gary is likely to be diagnosed with Generalized anxiety disorder because he has an excessive and persistent worry about future and this makes him think all the time about possible catastrophic scenarios which shows he is unable to control this though and he has an irrational worry which is part of this disorder.
