The correct option is
D Villus of intestine
Lacteals are lymphatic vessels found in small intestinal villi. While other nutrients such as amino acids and saccharides are absorbed into the blood stream, lacteals absorb fat. Occurring in the fingerlike villi of the ileum, lacteals have a milky appearance and drain into the lymphatic system. Before fat can pass into the lacteal, bile from the liver causes its emulsification into small droplets for attack by the enzyme lipase. So, the correct answer is option D.
