The correct option is
D Contaminated water
Jaundice is not a disease. It is a physical finding on an exam. It can be present in newborns if they have a rapid breakdown of blood or if they were born before their livers matured. It can happen when the bile duct gets blocked by a gallstone or a tumour of the pancreas. It can happen in many forms of liver disease. Among these is hepatitis A, a viral infection. It is spread by contaminated food or water. So jaundice can appear due to drinking water contaminated with the virus.
So, the correct option is 'Contaminated water'.
