Correct Answer is B

Explanation

A. Intracellular fluid: Intracellular fluid is inside the cells. Edema refers to fluid accumulation outside the cells, so this is incorrect.
B. Interstitial fluid: Edema is caused by the abnormal accumulation of fluid in the interstitial space, which is the space between cells in tissues.
C. Intracellular fluid and interstitial fluid: Edema is confined to the interstitial (extracellular) compartment, not intracellular.
D. Blood plasma: Although fluid may move from the plasma into the interstitial space, edema refers to fluid retention in tissues, not in the blood plasma.

Correct Answer is A

Explanation

A. Hydrostatic pressure of capillary blood: This pushes water out of capillaries into the interstitial space-it's the main driver of filtration at the arterial end of capillaries.
B. Osmotic pressure of plasma proteins: This pulls water back into capillaries, opposing outward flow.
C. Hydrostatic pressure of interstitial fluid: This would oppose outward filtration if significant, but it's usually low.
D. Intracellular hydrostatic pressure: This is not relevant to capillary filtration, which occurs between plasma and interstitial fluid.
