28. After electrolyzing a certain concentration of copper sulfate solution with an inert electrode at a certain temperature for a certain period of time, 0.1 mole of basic copper carbonate [Cu₂(OH)₂CO3] is added to the resulting solution, and the concentration and pH are restored to exactly the same level as before electrolysis (without considering the dissolution of carbon dioxide). What is the total number of electrons transferred during the electrolysis? (A) 0.4 mole (B) 0.5 mole (C) 0.6 mole (D) 0.7 mole (E) 0.8 mole
