Solution
The answer is the second one (or B): gastric juice.
Explanation for each option:
Saliva: This is the fluid produced in the mouth that contains enzymes like amylase, but it does not contain hydrochloric acid or pepsin.
Gastric juice: This is the digestive fluid produced in the stomach, which contains hydrochloric acid, water, pepsin, and mucus. These components help in the digestion of food.
Pancreatic juice: This is the fluid produced by the pancreas that contains digestive enzymes like amylase, lipase, and proteases, but it does not contain hydrochloric acid or pepsin.
