Correct:
C
Explanation
The incorrect match is Option C. The souring of milk is a biological process where lactose (milk sugar) is fermented into lactic acid by bacteria such as Lactobacillus. Nitric acid (HNO3) is a strong mineral acid and is not involved in the natural souring of milk.
The other options are correctly matched:
- Vinegar: Contains acetic acid (typically 5-8% by volume).
- Bones: The primary mineral component of bone is hydroxyapatite, which is a crystalline form of calcium phosphate.
- Gastric juice: The stomach secretes hydrochloric acid (HCl) to create an acidic environment for protein digestion and to eliminate pathogens.
