The correct answer is (c) Lipase.
Lipase is an enzyme that breaks down lipids, or fats, into smaller molecules that can be absorbed by the body. It is produced in the pancreas and secreted into the small intestine, where it helps to digest dietary fat.
Proteinase is an enzyme that breaks down proteins into smaller molecules that can be absorbed by the body. It is produced in the stomach and small intestine.
Amylase is an enzyme that breaks down carbohydrates, or starches, into smaller molecules that can be absorbed by the body. It is produced in the salivary glands and pancreas.
Saliva is a fluid that is produced in the mouth. It contains enzymes that help to break down carbohydrates and lipids, but it does not contain lipase.
