Which of the following antipsychotic drugs should haloperidol be substituted with in this patient?
- A. chlorprothixene.
- B. perazine.
- C. thioridazine.
- D. olanzapine.

Name the movement disorder caused by decades of a typical neuroleptic, then pick a drug with lower risk of it that still controls psychosis.
