Correct Answer

Explanation

Liver deaminates or breaks down excess amino acid into urea and glycogen. Pancreas secretes pancreatic juice which bears digestive enzymes (trypsin, amylopsin and lipase) and hormones called insulin and glycogen. Malpighian tubules are outgrowth from the digestive system of an insect between the mesenteron (mid gut) and ileum and are used as an excretory organ.
