In electroplating, the article to be electroplated serves as
A. Cathode
B. Anode
C. Electrolyte
D. Conductor

Hint: Cathode in an electroplating bath composed of a solution of the salt of the metal to be deposited. On the other hand, an anode of the same metal is chemically unaffected. Thus the electroplated material should be made of cathode and the positive radical from the electrolyte goes to the cathode and gets deposited there by the reduction process which is the grain of hydrogen.

Complete answer:
The article is electroplated for a few reasons: First to prevent it from corrosion and to improve the appearance of metal articles. To achieve the uniform and smooth coating of superior metal, a small current should be used -for a longer time. The electroplated object should also be placed as a cathode since the metal is always deposited at the cathode.
So the correct option is (A).

Note:
Various Processes are used for plating such as electroplating, electroless plating, anodizing are some major processes used today.
Electroplating was first introduced by Luigi Brugnatelli in 1805 by using the electrodeposition process for the electroplating of gold. But his finding was not noted and he was ignored by the French Academy of Science as well as Napoleon Bonaparte for this. But a few years later, John Wright had applied potassium cyanide as an electrolyte for gold and silver. He also found out that potassium cyanide was an efficient electrolyte. In 1840 The Elkington cousins used potassium cyanide as their electrolyte and designed a feasible electroplating technique for gold and silver. They got a patent for electroplating and this technique became widely famous throughout the world from England. The electroplating technique has gradually become more efficient and advanced by the use of more eco-friendly formulas and by using direct current power supplies.
