On physical exam, his blood pressure is 159/84, pulse is 74/min, and respirations are 12/min. He has a high frequency bilateral hand tremor elicited on finger-to-nose testing. His neurological exam is otherwise unremarkable. This patient should be started on which of the following medications?   (A) Alprazolam   (B) Primidone   (C) Propranolol   (D) Trihexyphenidyl
