Answer

Brief Explanations:

A heart - attack occurs when blood flow to a part of the heart is blocked, causing heart tissue death. Heart failure is a condition where the heart can't pump enough blood to meet the body's needs, resulting in systemic oxygen deficiency. Option A has the definitions reversed. Option B is incorrect as heart failure doesn't necessarily cause more heart - tissue death than a heart attack. Option D is wrong because heart failure causes oxygen deficiency, not an excess of oxygen.

Answer:

C. Heart tissue dies during a heart attack, while heart failure results in systemic oxygen deficiency.
