Answer:

Option (3) No change is correct.

Explanation:

A less reactive metal is called a noble metal. It does not readily react with gases when exposed or even in strong acids. Eg- Platinum and Gold. Aqua regia is used when we have to dissolve platinum or gold.

If the coating of a less reactive metal is broken, there will be no corrosion.

No change/reaction will take place when less active metal is broken.
