Solution

The correct option is C

Silver Sulphide


Silver when exposed to air reacts with sulphur oxides in air to form silver sulphides which is black in colour. Sulphur and nitrogen dioxide and trioxide gases present in the air act as pollutants and react with the surface of silver to form black compounds such as silver nitrate and silver sulphide.
