D
Verified Correct Answer: A.
Physical Principles & Numerical Solution
According to Faraday's Law, the mass of the substance deposited is directly proportional to the time for which the current flows, assuming a constant current. Therefore, the graph should show a linear increase in mass over time, which corresponds to option A
