Correct option is D
The correct answer is (d) Bile juice
Bile juice is a fluid produced by the liver and stored in the gallbladder.
The acidic food from stomach is made alkaline by the action of bile.
Bile is alkaline in nature as it contains organic salt known as bile salt.
It is released into the small intestine to help digest fats and neutralize the acidic chyme (partially digested food) coming from the stomach.
Bile juice contains bicarbonate, which helps raise the pH and make the chyme more alkaline (pH 6-7). This is necessary for the proper functioning of enzymes in the small intestine that break down carbohydrates and fats.
Pepsin is an enzyme in gastric juice that helps digest proteins.
