The correct answer is option B. Blood clotting.

Explanation:

Tissue profusion is the path of blood flow or the lymphatic fluid with the help of the lymphatic system or the circulatory system to a tissue area or organ. It is helpful to transport nutrients or eliminating waste from the blood so the adequate tissue profusion is required to maintain.

All three options except blood clotting are related to the transport of nutrients, oxygen of removal of waste with the help of a circulatory system of the lymphatic system. Blood clotting is a region specific event and does not involve profusion.

Thus, the correct answer is option - b. Blood clotting.
