None of the above

Explanation:
Detailed explanation-1: -The net filtration pressure (NFP) represents the interaction of the hydrostatic and osmotic pressures, driving fluid out of the capillary. It is equal to the difference between the CHP and the BCOP.
Detailed explanation-2: -At the arterial end of a vessel, the hydrostatic pressure is greater than the osmotic pressure, so the net movement favors water and other solutes being passed into the tissue fluid. At the venous end, the osmotic pressure is greater, so the net movement favors substances being passed back into the capillary.
Detailed explanation-3: -As blood moves from the arterial end to the venous end of a capillary, net filtration pressure: decreases as blood hydrostatic pressure decreases.
