ApoB is a protein component of which lipoprotein?

Explanation:
Apolipoprotein B acts as the structural and receptor-binding protein for several lipoproteins, with the form ApoB-100 being the one present on LDL particles. ApoB-100 is produced in the liver and enables LDL, as well as VLDL and IDL, to bind the LDL receptor and deliver cholesterol to tissues. In contrast, chylomicrons carry ApoB-48, and HDL is centered around ApoA-I. Among the options, LDL is the lipoprotein class most consistently described as containing ApoB-100, making it the best match.
