Answer:
As we learned..
Faraday's first law of electrolysis -
The mass of any substance deposited or dissolved at any electrode during electrolysis is directly propotional to the quantity of electricity passed through the solution.
W = Z I t
Z = mass of electrolyte get deposited
Z = electro chemical equivalent
j = 1 qupere
So option a is correct..
