Final answer:
The correct answer is b) Obsessive-compulsive disorder, an anxiety disorder featuring recurring, distressing thoughts and repetitive behaviors.
Step-by-step explanation:
Recurring unwanted thoughts, ideas, or sensations that drive you to do something repetitively are characteristic of Obsessive-compulsive disorder (OCD). This anxiety disorder leads to persistent and distressing thoughts (obsessions) and behaviors (compulsions) that the individual feels compelled to perform. OCD is different from schizophrenia, which involves symptoms such as hallucinations and delusions, and bipolar disorder, which is characterized by alternating periods of depression and mania. Therefore, the correct answer to the question is b) Obsessive-compulsive disorder.
