Solution

The correct option is B A: Zinc plate, B: Copper plate, C: Zinc sulphate solution
In the process of electroplating, the deposition of layers of one metal takes place on the other material.

In this process, the material on which the coating is to be done is connected as an electrode to the negative terminal, and the metal that is used for the deposition is connected to the positive terminal.

In this case, Avinash wants to add a zinc coating on the copper plate. So, the zinc plate has to be connected to A, i.e., the positive terminal and the copper plate has to be connected to the negative terminal, i.e., B.

Also, the item to be coated (Zinc) is placed into a container containing a solution of a salt of the same material (Zinc). Here, that solution containing the salt of zinc is the zinc sulphate solution (C).
