Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → (A) - (II), (B) - (I), (C) - (IV), (D) - (III)
A deficiency disease is caused by the lack of a nutrient in the diet; each vitamin has its own.
(A) Vitamin - K — this matches (II) Non-clotting of blood. Vitamin K is needed to make the proteins that make blood clot; without it, even a small cut keeps bleeding.
(B) Vitamin - C — this matches (I) Scurvy. Lack of vitamin C causes scurvy: bleeding, swollen gums, slow healing of wounds and weakness.
(C) Vitamin - D — this matches (IV) Rickets. Vitamin D helps the body take up calcium and phosphorus; children who lack it get soft, weak bones that bend.
(D) Vitamin - A — this matches (III) Color blindness, by elimination. The printed entry does not actually match: lack of vitamin A causes night blindness, poor vision in dim light, while colour blindness is an inherited condition, not a deficiency disease.
Note: It seems that there is a mistake in the original NTA paper, which prints (III) as ‘Color blindness’ when it should read ‘Night blindness’. The other three vitamins take (I), (II) and (IV), so vitamin A is left with (III), and the answer is not affected. The slip is in NTA’s list, not in your answer.
