Answer 1

The answer is B.)electroplating

Answer 2

Answer:

B.) electroplating

Explanation:

In the process of electroplating an expensive metal such as gold is coated over a base metal in thin layers in the presence of electricity. Electroplating takes place in an electrolytic cell, where the gold is the anode and the base metal is the cathode. A DC current is applied to complete the circuit. The gold ions are reduced and get deposited at the cathode.
