Neuro Stroke location

While on the Medicine rotations, a third-year medical student witnessed the arrival of a 63 year old woman with longstanding hypertension, diabetes, and hyperlipidemia. The woman was seen in the emergency room, where she was noted to have vomiting, left–sided Horner's syndrome, and loss of facial sensation on the left, but loss of body sensation on the right. A diffusion-weighted MRI and MRA are ordered. Before the radiologic studies are performed, the team asks the medical student where the problem lies. The best explanation for this patient's stroke presentation is occlusion of which artery?

A. Left middle cerebral artery
B. Right middle cerebral artery
C. Left anterior cerebral artery
D. Right anterior cerebral artery
E. Left posterior cerebral artery
F. Right posterior cerebral artery
G. Left posterior inferior cerebellar artery
H. Right posterior inferior cerebellar artery
