Which Statement Is True Concerning the Pressure Gradient Created by the Application

Which statement is true concerning the pressure gradient created by the application of external compression?

A) The gradient between the tissue hydrostatic pressure and the capillary filtration pressure is increased.
B) A second pressure gradient is formed between the higher pressure in the proximal portion and the lower pressure in the distal portion.
C) Elevating the extremity during the treatment does not alter the pressure gradients.
D) Spreading solid edematous matter over a larger area with external compression allows more lymphatic ducts to absorb the wastes.
