Final answer:
Sally's experience is most symptomatic of Obsessive-compulsive disorder (OCD) due to her repetitive and intrusive thoughts and behaviors related to cleaning her home.
Step-by-step explanation:
Sally's experience is most symptomatic of Obsessive-compulsive disorder (OCD).
OCD is characterized by repetitive and intrusive thoughts (obsessions) and behaviors (compulsions) that individuals feel driven to perform. In this case, Sally's focus on cleaning her home for 4 hours per day, with particular emphasis on straightening the fringe on her rugs in all five rooms, is a compulsive behavior. The fact that she feels the need to repeat this task 10 to 12 times per day further suggests OCD.
OCD is a mental disorder that can significantly impact a person's daily life and functioning. If Sally's behaviors interfere with her ability to engage in other activities or causes distress, it may be beneficial for her to seek professional help and treatment.
