Actually hydrogen sulfide is a oxidizing agent so when the bras is oxidize with hydrogen sulfide its convert to brass oxide.
Like iron is reacts with oxides then its changes iron color. Like that brass converts into colorless.

Actually, Brass is not a simple metal but an alloy i.e. a mixture of Cu and Zn. Generally sulphur in air is very reactive to copper mixtures. So the answer is B.
