Question 3

Coronary artery disease (CAD) is most commonly caused by atherosclerosis, which is the buildup of plaque (fatty deposits, cholesterol, etc.) in the coronary arteries, narrowing them and reducing blood flow to the heart. Infarction is a result of blocked blood flow (like a heart attack), edema is fluid accumulation, and congestive heart failure is a condition often resulting from CAD or other heart issues, not the primary cause of CAD.

The prefix "atelo - " in medical terminology means "incomplete". For example, atelocardia means an incomplete development of the heart. Arteriole refers to a small artery, blood serum is the liquid part of blood, and vein is a blood vessel carrying blood to the heart—none of these match the meaning of the prefix "atelo - ".

Answer:

A. atherosclerosis
