What vitamin is known to cause protein coagulation?

1. Vitamin A

2. Vitamin K

3. Vitamin C

4. Vitamin D

The correct answer is: Vitamin K

Vitamin K is essential for the process of blood coagulation, which involves protein coagulation as part of the body's mechanism to stop bleeding. It plays a crucial role in the synthesis of certain proteins that are needed for blood coagulation and the prevention of excessive bleeding. Specifically, vitamin K is involved in the production of clotting factors that enable the blood to clot effectively when there is an injury. The other vitamins listed do not have a primary role in protein coagulation. Vitamin A is mainly associated with vision and skin health. Vitamin C is known for its role in collagen synthesis, immune function, and as an antioxidant. Vitamin D primarily helps regulate calcium and phosphate in the body, essential for maintaining bone health. Thus, vitamin K stands out as the vitamin directly linked to the coagulation of proteins in the context of blood clotting.
