Answer A. Watershed necrosis result from hypoperfusion (a lack of blood flow), which can be caused by congestive heart failure, severe atherosclerosis of the carotid arteries, or systemic hypotension (shock).
the lesion is in the region of overlapped distribution between the anterior cerebral artery and the middle cerebral artery. The patient classically presents with weakness of proximal arm and leg muscles and preservation of distal strength.

Systemic hypotension or shock causing hypoperfusion is very likely to present in the setting of a extensive MI as with the case here. I'd still stick with C.. jack, whats the answer?
