Non-HDL cholesterol encompasses which of the following lipoproteins?

Explanation:
Non-HDL cholesterol represents the cholesterol content of all atherogenic lipoproteins that carry apolipoprotein B, namely VLDL, IDL, LDL, and lipoprotein(a). Because it includes all these apoB-containing particles, the description listing VLDL, IDL, Lp(a), and LDL is the correct one. HDL particles are protective and are not included in non-HDL cholesterol. Chylomicrons are not the focus of the standard non-HDL measure in fasting lipid panels, and non-HDL is defined by including apoB-containing lipoproteins, not excluding them.
