ACA
MCA
Basilar Artery
Carotid Artery

The correct answer is: MCA

A The anterior cerebral artery (ACA) may be affected in a stroke but is not the most common artery occlusion. C: The basilar artery is a common location for strokes, but it is not the most commonly occluded artery. D: The carotid artery can also be affected in a stroke, but it is not the most commonly occluded artery. The correct answer is the middle cerebral artery (MCA), as it supplies blood to a large portion of the brain and is a common location for blockages leading to a stroke.
