Option (4)

The excretion of the vitamins that are fat-soluble, is not a function of the urinary system. It is because the fatty substances are excreted from the body at a very slow rate. They are mostly absorbed by the liver, tissue and some amount of it are absorbed by the small intestine. It can cause toxicity in the body as they are eliminated slowly.
