Question

coronary artery disease is caused by the
plaque
carbon dioxide
pressure
hypertension

Explanation:

Coronary artery disease (CAD) is primarily caused by the buildup of plaque (fatty deposits, cholesterol, etc.) in the coronary arteries, which narrows them and restricts blood flow. Carbon dioxide is a gas involved in respiration, not a direct cause of CAD. Pressure is too vague, and hypertension (high blood pressure) is a risk factor but not the direct cause of the disease's development (plaque buildup is the direct pathological cause here). So the correct option is the one with "plaque".

Answer:

A. plaque
