Vitamin K is vital for synthesizing clotting factors II, VII, IX, and X in the liver. Deficiency leads to excessive bleeding and poor wound healing. Dietary sources include leafy greens, broccoli, and fermented foods. Newborns receive a Vitamin K injection at birth to prevent hemorrhagic disease, as breast milk alone is insufficient.
Final Answer: Option C - Vitamin K
