Explanation of Each Match

(A) Fish liver oil → Vitamin A (II)

Fish liver oil (like cod liver oil) is a rich source of retinol (Vitamin A). Vitamin A is essential for vision, epithelial tissue health, and immunity. Deficiency leads to night blindness.

(B) Citrus fruits → Vitamin C (I)

Citrus fruits (orange, lemon, amla) are rich in ascorbic acid (Vitamin C). It is important for collagen synthesis, wound healing, and immunity. Deficiency causes scurvy.

(C) Exposure to sunlight → Vitamin D (IV)

Sunlight helps convert 7-dehydrocholesterol in skin into Vitamin D. Vitamin D regulates calcium and phosphorus metabolism. Deficiency leads to rickets and osteomalacia.

(D) Curd → Vitamin $B_{12}$ (III)

Curd contains Vitamin $B_{12}$ produced by microbial activity. Vitamin $B_{12}$ is vital for red blood cell formation and nerve function. Deficiency leads to pernicious anemia.
