Explanation:

In laminar blood flow, due to the friction between blood and the vessel walls, the flow velocity is lowest near the walls and highest in the center of the blood vessel. So the correct option is the one stating "In the center of the blood vessel".

Answer:

C. In the center of the blood vessel (assuming the options are labeled A, B, C as per typical multiple - choice, with A: Blood flows at the same rate in the center and at the walls, B: Near the walls of blood vessels, C: In the center of the blood vessel)
