Obsessions and intrusive thoughts, while compulsion are a. Appropriate words b. Unpleasant desires c. Manifest content d. Rigid behaviors

d. Rigid behaviors.

The correct answer is b. Unpleasant desires.

Obsessions and intrusive thoughts refer to unwanted, repetitive, and distressing thoughts or mental images that often cause anxiety or discomfort. Compulsions, on the other hand, are repetitive behaviors or mental acts that a person feels driven to perform in response to an obsession, in order to alleviate anxiety or prevent a feared outcome. Both obsessions and intrusive thoughts can be considered unpleasant desires because they are unwanted and cause distress to the person experiencing them.
