Actually transition elements are colored elements. Here Zn & Cu are the transition elements ,these composition is the brass. But it gets discolored in air because of presence of Hydrogen sulphide in the air.It discolored the color of the brass. So it appears as discolored.

Presence of air and water in atmosphere.

I think that option a is correct because O2 can react with brass and can discolored it

It is because the presence of mixture of hydrogen and sulphide and brass is a type of thing which has a color very light and mixture is non temperature (hot and cold type of temperature) so it gets discolored.this is better answer.etc
