Which vitamin is fat-soluble and essential for blood clotting?

Explanation:
Fat-soluble vitamins are stored in the body's fat tissues and liver. The vitamin that fits the requirement of being fat-soluble and essential for blood clotting is vitamin K. It activates the proteins that form and regulate the clotting cascade, enabling them to bind calcium and function properly to stop bleeding. Without enough vitamin K, the coagulation process is impaired, leading to prolonged bleeding. The other vitamins have different primary roles—A supports vision and immunity, D helps regulate calcium and bone health, and E acts mainly as an antioxidant—so they don’t directly drive the clotting process.
