Capillaries have thin walls, which allows for efficient diffusion of gases, nutrients, and waste products between the plasma and interstitial fluid. The thin walls also allow for easier exchange of fluids and solutes between the two compartments. Fewer capillaries or a great distance between cells and capillaries would limit the efficiency of this exchange. Therefore, the best choice is C - thin walls.
