B. Lactic acidII. Spinach
C. Oxalic acidIII. Citrus fruits
D. Ascorbic acidIV. Vinegar

  • A.A-II, B-III, C-IV, D-I
  • B.A-I, B-II, C-III, D-IV
  • C.A-IV, B-I, C-II, D-III
  • D.A-II, B-IV, C-I, D-III

Answer: C

The correct matching is A-IV, B-I, C-II, D-III.

  • A. Acetic acid is found in vinegar (IV).
  • B. Lactic acid is found in curd (I).
  • C. Oxalic acid is found in spinach (II).
  • D. Ascorbic acid (vitamin C) is found in citrus fruits such as oranges and amla (III).

The other codes give vinegar, curd or spinach the wrong acid; for example, citric acid rather than oxalic acid is the acid of lemons.
