Question

the stomach secretes: a saliva. b sulfuric acid. c water. d hydrochloric acid.

Explanation:

Saliva is secreted by salivary glands. Sulfuric acid is not a substance secreted by the stomach. While the stomach has some water content, it is not the main secretion. The stomach secretes hydrochloric acid which helps in digestion (e.g., activating pepsinogen to pepsin, killing bacteria in food).

Answer:

D. hydrochloric acid
