C) heat transfer.
D) hydrogen ion transfer.
E) pinocytosis.
Kidney Dialysis
A medical treatment for removing waste and excess water from the blood, acting as an artificial replacement for lost kidney function.
Active Transport
Use of a plasma membrane carrier protein to move a molecule or ion from a region of lower concentration to one of higher concentration; it opposes equilibrium and requires energy.
Diffusion
Movement of molecules or ions from a region of higher to lower concentration; it requires no energy and tends to lead to an equal distribution (equilibrium).

Final Answer :
B
Explanation :
Kidney dialysis works by diffusion, which is the movement of solutes from an area of higher concentration to an area of lower concentration. During dialysis, a patient's blood is filtered through a semipermeable membrane, allowing waste products and excess fluids to diffuse out of the blood and into a dialysis solution. This process helps to mimic the function of the kidneys, which normally filter waste products from the blood.
