Answer 1

E. none of the above
LDL is the main carrier of cholesterol. The LDL is removed from the circulation by either LDL receptors or by nonreceptor mechanisms, i.e., macrophages. When there is a decrease in LDL receptors or when LDL levels exceed receptor availability, the amount of LDL that is removed by scavenger cells is greatly increased. The uptake of LDL by macrophages in the arterial wall can result in the accumulation of insoluble cholesterol esters, the formation of foam cells, and the development of atherosclerosis.

Answer 2

Me W is correct, the answer is E. I would add, that Cholesterol must be Oxidized before the scavenger receptors can uptake it. It is the oxidation of cholesterol that makes it atherogenic.
