C Correct answer
Explanation

The mass of a substance altered at an electrode during electrolysis is directly proportional to the quantity of electricity transferred at that electrode. Quantity of electricity refers to the quantity of electrical charge, typically measured in coulomb. For a given quantity of DC electricity (electric charge), the mass of an elemental material altered at an electrode is directly proportional to the element's equivalent weight.
