The description matches that of a micelle, which is a structure formed by the emulsification of dietary fat in the small intestine, where fat globules are broken down into smaller droplets and coated by bile salts synthesized in the liver. The resulting micelle can be absorbed by the intestinal cells for further processing and transport to the rest of the body. Secretions of the gall bladder (A) and pancreas (D) contribute to the process of fat digestion and absorption but do not match the described structure. Chylomicron (B) is a lipoprotein particle that carries dietary fats and fat-soluble vitamins from the intestine to the bloodstream, but it is formed after the micelle is absorbed by the intestinal cells rather than inside the lumen of the intestine.
