A) Hydrochloric acid (HCl) is indeed a major component of gastric juice in the stomach, aiding digestion. (Correct)
B) Acetic acid (CH₃COOH) is the main active component of vinegar, typically present as a dilute solution (around 5-8%). (Correct)
C) Tamarind paste is known for its sour taste, which is primarily due to the presence of tartaric acid. While some other acids might be present in smaller quantities, oxalic acid is not the main acid found in tamarind. Oxalic acid is abundant in foods like spinach, rhubarb, and sorrel. (Incorrect)
