Answer:
The correct answer is option B) chromium.
Explanation:
- In order to prevent corrosion, chromium is utilised to coat the machinery and its components.
- Compared to iron, metals like nickel and chromium are less reactive. As a result, iron is electroplated with deposits of nickel or chromium to stop corrosion.
- Because copper corrodes when exposed to moisture and high temperatures, copper plating is not recommended for machinery parts.
- In order to prevent corrosion and give them a good shine, machinery parts are often chromium plated.
- B) Chromium is the right answer.
