Match List-I (vitamins) with List-II (Deficiency diseases)

Choose the correct answer from the options given below:

(A)-(IV), (B)-(III), (C)-(II), (D)-(I)

The correct answer is Option (3) → (A)-(IV), (B)-(III), (C)-(II), (D)-(I)

(A) Vitamin C $\rightarrow$ (IV) Scurvy: Vitamin C (ascorbic acid) is essential for collagen synthesis. Its deficiency leads to scurvy, characterized by bleeding gums, skin spots, and slow wound healing.

(B) Vitamin K $\rightarrow$ (III) Increased blood clotting time: Vitamin K is a critical factor in the synthesis of several proteins needed for blood coagulation. Without it, blood takes much longer to clot, leading to excessive bleeding.

(C) Vitamin D $\rightarrow$ (II) Rickets: Vitamin D helps the body absorb calcium. A deficiency in children causes rickets, where the bones become soft, weak, and deformed.

(D) Vitamin A $\rightarrow$ (I) Night blindness: Vitamin A is vital for maintaining healthy vision, particularly in low-light conditions. Its deficiency leads to nyctalopia, or night blindness.
