Answer: 3. (c) and (d) are correct

Key idea: Dialysis removes wastes, but cannot replace endocrine functions of the kidney.

(a) and (b) are wrong: dialysis removes urea and excess potassium, so wastes do not build up.
(c) is correct: the kidney activates vitamin D, needed for calcium absorption from the gut, and this is lost in kidney failure.
(d) is correct: the kidney produces erythropoietin, so RBC production falls.

Hence (c) and (d) are correct.
