Canvas Classes · Accepted Answer

Role of Vitamin K:

Vitamin K (phylloquinone) is essential for the synthesis of clotting factors in the blood (factors II, VII, IX, X — the prothrombin group).

Deficiency of Vitamin K:
- Impairs synthesis of clotting factors
- Blood takes longer to clot → increased blood clotting time
- Can lead to excessive bleeding (haemorrhage)

Why other options are wrong:
- Fragility of RBCs: caused by Vitamin E deficiency
- Cheilosis: caused by Vitamin B₂ (Riboflavin) deficiency
- Decrease in clotting tim
