Final answer:
The correct answer is D, where repeatedly thinking about one's own death is an obsession, and repeatedly washing your hands is a compulsion. These terms reflect the patterns of thought and behavior consistent with Obsessive-Compulsive Disorder (OCD).
Step-by-step explanation:
Repeatedly thinking about your own death is to obsession as repeatedly washing your hands is to compulsion. The correct answer to the fill-in-the-blank question is D. Obsession refers to persistent intrusive thoughts, images, or urges that cause distress or anxiety. In this case, the thought of one's death is an example of an obsession. Compulsion refers to repetitive behaviors or mental acts that an individual feels driven to perform in response to an obsession, or according to rules that must be applied rigidly, often to reduce distress or prevent some dreaded event or situation. Compulsive hand-washing is a typical behavior exhibited by individuals with Obsessive-Compulsive Disorder (OCD). Therefore, the obsessions are the intrusive thoughts about death, and the compulsions are the actions taken, such as hand washing, to alleviate the anxiety caused by these thoughts.
