B) fluid will tend to accumulate in tissues
C) the pH of the interstitial fluids will increase
D) plasma proteins will escape through the endothelium of the capillaries

If the osmotic pressure on the venous side of capillary beds is lower than the hydrostatic pressure, fluid will tend to accumulate in tissues. This is because hydrostatic pressure forces fluid out of the capillaries, while osmotic pressure pulls fluid back in, and if the osmotic pressure is lower, then the pull of fluid back into the capillaries is weaker than the force pushing it out. This can lead to edema and swelling of tissues. The other answer choices are not related to the pressure differentials in capillary beds.
