Expert Answer
Highly reactive metals with lower reduction potential than hydrogen are not obtained by electrolysis of an aqueous solution of their salts because their cations cannot be reduced at the cathode in the presence of water.
Generally, d-block elements are less reactive and hence can be prepared by electrolysis of their salt solution.
Hence option A: Cu is the right answer.
