The correct option is C Intestine
Pancreatic juice contains pancreatic amylase, lipase and trypsin, trypsin converts polypeptides into the dipeptides in the first part of small intestine i.e., duodenum. The succus entricus in the third part of small intestine i.e., ileum converts dipeptides into the amino acids which are absorbed by the wall of the intestine. Thus, the correct answer is option C.
