Correct Answer: C
Rationale: The correct answer is C: Improvement in tardive dyskinesia. Tardive dyskinesia is a side effect of long-term antipsychotic use, like chlorpromazine. Quetiapine (Seroquel) is an atypical antipsychotic with a lower risk of causing tardive dyskinesia. By discontinuing chlorpromazine and switching to quetiapine, there is a higher likelihood of improvement or resolution of tardive dyskinesia symptoms. Options A and B are incorrect as they are related to other movement disorders caused by antipsychotics. Option D is incorrect as anticholinergic symptoms are not directly related to tardive dyskinesia improvement with the medication switch.
