Solution

The correct option is B CuSO4
Answer is B.
Here, the solution can be a salt solution consisting of copper ions like copper sulphate solution which is metallic salt solution.
During the electroplating process or the purification process rather, the copper from the impure plate is transferred to the pure copper plate , through the electrolytic copper sulphate solution.
Hence, The solution Y used in the cell is copper sulphate solution.
