Neuro Right Sided Weakness and Anesthesia and Lateral Gaze Palsy!

A 65-year-old patient, with 2-year history of atrial fibrillation, has come to the emergency room complaining about a sudden onset of right-sided weakness in both his arm and leg. In physical examination, the tactile sensation was impaired in right arm and right leg. His speech is intact and he is oriented and alert. When the patient looked at the wall on the left side, his right eye adducted very well but his left eye stayed in the middle. Which of the following arteries is affected?
A) Right Posterior inferior cerebellar artery
B) Right Anterior inferior cerebellar artery
C) Right Posterior cerebral artery
D) Right Paramedian branches of basilar artery
E) Left Posterior inferior cerebellar artery
F) Left Anterior inferior cerebellar artery
G) Left Posterior cerebral artery
H) Left Paramedian branches of basilar artery
I) Vertebral artery
J) Anterior spinal artery

right-sided weakness in both his arm and leg --- Contralateral Corticospinal tract
tactile sensation was impaired in right arm and right leg -- Contra Lat. lemniscus
Left abducens palsy -- fibers of left abducens


answer has to on the left side.
I would say:
H) Left Paramedian branches of basilar artery - it's medial inferior pontine syndrome
