Match List I with List II
|
List I Vitamin |
List II Deficiency |
| A. Vitamin D | I. Slow blood clotting |
| B. Vitamin C | II. Night blindness |
| C. Vitamin K | III. Rickets |
| D. Vitamin A | IV. Scurvy |
Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → A-III, B-IV, C-I, D-II
Vitamins are needed in small amounts, and the lack of each one causes a typical deficiency disease. Vitamins A, D, E and K are fat soluble; the B group and vitamin C are water soluble.
(A) Vitamin D — This matches (III) Rickets. Vitamin D is needed for the use of calcium and phosphate in bones; its lack causes bone deformities in children (rickets) and soft bones in adults (osteomalacia).
(B) Vitamin C — This matches (IV) Scurvy. Lack of vitamin C (ascorbic acid) causes scurvy, with bleeding gums.
(C) Vitamin K — This matches (I) Slow blood clotting. Vitamin K is needed to make the clotting factors, so its deficiency increases the blood clotting time.
(D) Vitamin A — This matches (II) Night blindness. Vitamin A deficiency causes xerophthalmia (hardening of the cornea) and night blindness.
