• C. Nephritis

Answer 1

The correct option is A

Hemodialysis

Hemodialysis is a process by which wastes from the body are removed by using an artificial kidney. A series of tubes, made up of semipermeable membrane are placed in a dialysis solution to remove the wastes and purified blood is pumped back into the body. The dialysis fluid contains all the constituents of plasma except urea. Thus, urea gets removed from the blood by diffusion.
