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.
