(A)For the same electrolyte, the mass of a substance produced or consumed at an electrode is directly proportional to the quantity of electricity passed through the electrolytic cellCorrect
(B)When same quantity of electricity is passed through different electrolytes, the amount of product obtained is proportional to their equivalent mass
(C)When same quantity of electricity is passed through different electrolytes, the amounts of products obtained are proportional to their molecular masses
(D)For the same electrolyte, the mass of a substance produced or consumed at an electrode is inversely proportional to the quantity of electricity passed through the electrolytic cell
