Low concentration triglycerides

Low levels of LDL cholesterol

High levels of high-density lipid (HDL)

Answer and Explanation

The Correct Answer is A

A.   LDL cholesterol, often referred to as "bad" cholesterol, is a major risk factor for atherosclerosis and PVD. High levels of LDL contribute to the buildup of plaque in the arteries, which can lead to these conditions.
B.   While high triglycerides can be a risk factor, low triglycerides are generally not associated with increased risk of atherosclerosis or PVD.
C.   Low LDL cholesterol is actually considered beneficial and can reduce the risk of heart disease.
D.   HDL cholesterol, often called "good" cholesterol, helps remove LDL cholesterol from the bloodstream. High levels of HDL are actually protective against heart disease and PVD.
