Detailed Solution

According to Faraday's second law of electrolysis ''The masses of different ions liberated at the electrodes, when the same amount of electricity is passed through the electrolytic solution are directly proportional to their respective chemical equivalent weights”.

If equal charge is given then equal number of equivalent get deposited.

In the given problem, equal charge is supplied to each ion and each ion has the same charge/mass ratio. This depicts that same mass of A, B, and C deposit.
