Vitamin K (List-I, item A) is required for the synthesis of prothrombin that helps in blood clotting.
Deficiency of vitamin K therefore leads to uncontrolled bleeding or $$\text{haemorrhage}$$ (List-II, item III).
Hence $$A \rightarrow III$$.
Vitamin A (List-I, item B) maintains the health of the cornea and is necessary for the formation of the visual pigment rhodopsin.
Its prolonged deficiency produces dryness of the conjunctiva and cornea, a disorder called $$\text{xerophthalmia}$$ (List-II, item IV).
Hence $$B \rightarrow IV$$.
Vitamin B$$_1$$ (thiamine, List-I, item C) plays a key role in the oxidative decarboxylation of pyruvic acid during carbohydrate metabolism.
Lack of thiamine results in impaired energy production leading to the disease $$\text{beri beri}$$ (List-II, item I).
Hence $$C \rightarrow I$$.
Vitamin E (tocopherol, List-I, item D) functions as an antioxidant and protects cell membranes, especially in reproductive tissues.
In males, its deficiency can cause degeneration of germinal epithelium giving rise to $$\text{sterility}$$ (List-II, item II).
