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)-(II), (D)-(I)
A deficiency disease shows the job the vitamin does in the body, so each match follows from that job.
(A) Vitamin K — this matches (III) Non-clotting of blood. Vitamin K is needed to make the clotting factors, such as prothrombin, so without it a wound keeps bleeding.
(B) Vitamin A — this matches (IV) Night blindness. The retina needs vitamin A to make rhodopsin, the pigment for seeing in dim light.
(C) Vitamin B2 — this matches (II) Cracking of skin. A lack of riboflavin (B2) causes cracks at the corners of the mouth, sore lips and a rough, scaly skin.
(D) Vitamin B1 — this matches (I) Beriberi. Thiamine (B1) helps the body get energy from carbohydrates; its lack harms the nerves and heart, causing beriberi.
