The correct option is B cellulose
Pancreatic juice is a liquid secreted by the pancreas. It contains various digestive enzymes such as trypsinogen, chymotrypsinogen, carboxypeptidase, pancreatic lipase, amylase.
Trypsin, chymotrypsin and carboxypeptidase help in the breakdown of proteins. Pancreatic lipase helps to break fats. Amylase breaks down the carbohydrates.
There is no enzyme in the human body that can digest cellulose, hence it is released in the faeces undigested.
