Correct Answer: Blood clotting

Solution : The correct option is Blood clotting.

Vitamin K is a fat-soluble nutrient that is crucial for blood clotting, and bone health. It comes in two forms: K1, which is found in green leafy vegetables, and K2, which is created by gut bacteria, and found in fermented meals. Vitamin K promotes bone mineralisation by facilitating the synthesis of proteins required for normal blood coagulation.
