Because of carotid atherosclerosis

Answer(B) The cerebral arteriogram shown in Figure reveals severe stenosis of the common carotid artery proximal to its bifurcation, as well as
small lesions in the more distal vessels.Common manifestations are transient monocular blindness (amaurosis fugax), hemiparesis, hemisensory loss, aphasia, and homonymous visual field defects. Ataxia would be an unusual feature of carotid disease and, if present, would suggest involvement of the vertebrobasilar
arteries, which results in dysarthria, diplopia, and vertigo.
