The correct option is D Digestive system
Any condition that disrupts the movement of bilirubin from the blood to the liver and out of the body can cause Jaundice. Bilirubin is a waste product created when red blood cells are broken down. In the bloodstream it is transported to the liver, where it is combined with a digestive fluid called bile. This eventually passes out of the body in urine or stools. So that is why jaundice is a disorder of the digestive system. This is also the reason why our stools are yellow in color, usually.
