What is the primary component of gastric juice?

digestive secretions of the stomach glands consisting chiefly of hydrochloric acid and mucin and the enzymes pepsin and rennin and lipase
underground water that is held in the soil and in pervious rocks
the energy produced by heat within the earth
a monosaccharide sugar that has several forms

The correct answer is: digestive secretions of the stomach glands consisting chiefly of hydrochloric acid and mucin and the enzymes pepsin and rennin and lipase

Gastric juice is primarily made up of digestive secretions of the stomach glands. It consists mainly of hydrochloric acid and mucin, which help break down food, as well as enzymes like pepsin, rennin, and lipase. Option B, underground water, does not make up gastric juice and is not even a component of it. Option C, energy produced by heat within the earth, is not related to gastric juice at all. Option D, a monosaccharide sugar, is not the primary component of gastric juice, though it may be found in some foods that we eat. Overall, option A is the most correct answer because it provides a detailed description of the composition of gastric juice.
