Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → A-I, B-III, C-IV, D-II
Many foods taste sour because they contain natural organic acids; each source has its own main acid.
(A) Vinegar — this matches (I) Acetic Acid. Vinegar is a dilute solution (about 5–8%) of acetic acid, made by fermenting alcohol.
(B) Orange — this matches (III) Citric Acid. Citrus fruits such as oranges and lemons owe their sour taste to citric acid.
(C) Curd — this matches (IV) Lactic Acid. Bacteria (Lactobacillus) turn the milk sugar lactose into lactic acid, which sets the milk into curd.
(D) Tomato — this matches (II) Oxalic Acid. Tomatoes (like spinach) contain oxalic acid.
