b) Citric Acid: Citric acid is another naturally occurring organic acid found in citrus fruits like lemons and oranges. It is widely used as a food preservative, flavor enhancer, and cleaning agent. While both citric acid and vitamin C are acids, they have different chemical structures and properties. Therefore, option b) is incorrect.
