The correct option is D All of the above
Bile salts (bile acids) are the major organic component of bile. The liver uses active transport to secrete bile salts. The function of bile salts in the duodenum is to solubilize ingested fat and fat soluble vitamins, facilitating their digestion and absorption. From the liver, bile flows from the intrahepatic collecting system into the right or left hepatic duct, then into the common hepatic duct.
