• D. aluminium

Answer 1

The correct option is C

chromium

Electroplating:

1. The process of aligning another metal onto metal is known as electroplating.
2. This is accomplished with the help of an electroplating apparatus that consists of a brine solution, a battery, wires, and alligator clips that hold carbon rods attached to the metal to be electroplated and the metal to be layered.
3. Because chromium shines and is scratch-resistant, it is used in electroplating to give products a gleaming appearance.

Hence, Option(C) is correct.
