The main function of vitamin K in the body is

Correct option is A

Vitamin K is primarily responsible for blood coagulation (or clotting). It plays a crucial role in synthesizing certain proteins called clotting factors that help blood to clot, preventing excessive bleeding when injuries occur.
Information Booster: Vitamin K is essential for the proper functioning of the blood clotting system. Without it, the body would struggle to form blood clots, leading to excessive bleeding. It is found in two main forms:
· Vitamin K1 (phylloquinone), which is found in leafy green vegetables.
· Vitamin K2 (menaquinone), found in fermented foods and animal products.
Vitamin K’s role in clotting is vital for wound healing and preventing internal bleeding.
Additional Knowledge on Incorrect Options:
· Acts as an antioxidant (Option B): Vitamin E (not K) is primarily known for its antioxidant properties, helping protect cells from oxidative damage.
· Maintenance of vision (Option C): This is the role of Vitamin A, not Vitamin K.
· More than one of the above (Option D): This is incorrect because only blood coagulation is the main function of Vitamin K.
· None of the above (Option E): This is incorrect, as blood coagulation is the correct function of Vitamin K.
