helium gas

sulphur

- Silver tarnishes due to a reaction with sulfur compounds in the air, forming black silver sulfide.

- Option 1: Vapour - Pure water vapour itself doesn't cause silver to tarnish.

- Option 2: Carbon dioxide - Doesn’t react significantly with silver to cause tarnishing.

- Option 3: Helium gas - An inert gas that doesn’t react with silver.

- Option 4: Sulphur - When silver reacts with sulfur, it forms silver sulfide, which is black.
