Final answer:
Sally's thorough cleaning habits and repetitive fringe-straightening behavior indicate that her experience is most symptomatic of A. Obsessive-Compulsive Disorder (OCD).
Step-by-step explanation:
Sally's behavior of ritualistically cleaning and ensuring that the fringe on her rugs is straight in all five rooms, repeatedly doing this 10 to 12 times daily, is most symptomatic of Obsessive-Compulsive Disorder (OCD). OCD is characterized by persistent thoughts (obsessions) and repetitive behaviors (compulsions) that an individual feels compelled to perform. Sally's considerable time spent on cleaning and the compulsion to straighten the fringes repeatedly, even when they are likely already clean, demonstrates a behavior pattern commonly associated with OCD.
The student's experience is most symptomatic of Obsessive-Compulsive Disorder (OCD). OCD is characterized by recurrent, unwanted thoughts (obsessions) and/or repetitive behaviors (compulsions) that an individual feels compelled to perform. Sally's repetitive and time-consuming cleaning of her home, particularly her focus on straightening the fringe on her rugs in all five rooms, suggests an obsession with cleanliness and order. This behavior is likely interfering with her daily life and causing distress.
