A	oxygenated blood supply to organs are lowered
B	oxygenated blood supply to organs are stopped
C	deoxygenated blood supply to organs are lowered
D	None of the above

Detailed explanation-2: -Ischemia-Temporary deficiency of blood and oxygen in a portion of the body, often caused by a blockage in the blood vessel supplying that part.

Detailed explanation-3: -A myocardial infarction occurs when there is a narrowing or occlusion of a coronary artery due to atherosclerosis (plaque buildup due to cholesterol). In an infarction blood supply is insufficient to the contracting myocardium and oxygen supply does not meet oxygen demand causing cell death.
