Which statement best describes a heart attack? A. Certain blood vessels expand

B. Certain blood vessels shrinks

C. Blood vessels are normal

D. Certain blood vessels are blocked by fatty acids

I think number D is correct

D. Certain blood vessels are blocked by fatty acids

Explanation:

A heart attack occurs when the flow of blood to the heart is blocked. The blockage is most often a buildup of fat, cholesterol and other substances, which form a plaque in the arteries that feed the heart (coronary arteries). Sometimes, a plaque can rupture and form a clot that blocks blood flow.
