Correct Answer: C
Solution :
Vitamin-K (Naphthoquinone) is an essential cofactor involved in synthesis of prothrombin in liver cells, which is in turn essential for blood clotting, prevention of haemorrhage and excessive bleeding in wounds. This vitamin is synthesized by colon bacterium, hence a diatary source is not usually necessary. Vitamin-D (ergocalciferol) is synthesized by herbivorous animals in the cells of their skin in sunlight. Vitamin-C (ascorbic acid) can be easily obtained from citrus and other fruits, tomatoes, green leafy vegetables, potatoes, carrot etc. Vitamin-B (thiamine) is found in rice bran, wheat flour and other cereals, green vegetables, nut, pulses, egg, yeast, liver etc.
