Which of the following is a risk factor for coronary heart disease?

Explanation:
High blood cholesterol increases the risk of coronary heart disease because excess cholesterol, especially LDL, can deposit in artery walls and form plaques. These plaques narrow and stiffen arteries, reducing blood flow to the heart and raising the chance of a heart attack. In contrast, a balanced diet, regular exercise, and not smoking are protective for heart health, helping to keep cholesterol and other risk factors in check. So the factor that raises risk is high blood cholesterol.
