The correct option is D Bile pigments
Fat builds up in the liver cells, when the liver fails to break down, transfer and store fat effectively, causing abnormal liver function and inflammation, which can lead to liver scarring (known as cirrhosis). The main pigment in bile, bilirubin, is a waste product that is formed from hemoglobin (the protein that carries oxygen in the blood) and is excreted in bile. About half the bile secreted between meals flows directly through the common bile duct into the small intestine. The rest of the bile is diverted through the cystic duct into the gallbladder to be stored. Liver stores the fat soluble vitamins (A,D, E & K) and Vit B12.
