Solution
The correct option is C
Left side of the membrane consists of blood while the right side is the dialysate side (because RBC is never present at the dialysate side). Blood cells, protein and other important things remain in blood because they are too big to pass through the membrane. Smaller waste products in the blood, such as urea, creatinine, potassium and extra fluid pass through the membrane and are washed away. Options a and d are incorrect because they show diffusion of protein while option b is incorrect as it depicts diffusion of erythrocytes out of the membrane. Hence, correct option is c.
