b. Vitamin K deficiency inhibits the blood's ability to clot.

Explanation:

The main form is vitamin K1 (phylloquinone); followed by vitamin K2 (menaquinone), formed from the bacterial action on the large intestine tract and a third compound, vitamin K3 (menadione), a synthetic fat-soluble molecule. These vitamins can be found in many foods: in green vegetables (lettuce, cauliflower and spinach), in tomatoes, Brazil nuts, cashews, potatoes, contained in soybean oil, egg yolk, milk and to a lesser extent in wheat and oats.

Vitamin K participates in blood clotting, its deficiency can make it difficult to stop bleeding. Also causing damage to the body when in excessive concentration, for example: dyspnea (shortness of breath), and chest pain in adults with high vitamin K1 disorder and hyperbilirubinemia in newborns whose mothers in gestation underwent treatment with based on vitamin K3.
