In most of the answers it is said that sulphur reacts with brass but it cannot be ignored that hydrogen sulphide is a compound sulphur not only can react with brass.

Oxygen makes metal corrode, so I think A might be a right answer too.

Hydrogen sulfide:

Chemical Compound:
Hydrogen sulfide is a chemical compound with the formula H 2S. It is a colorless gas with the characteristic foul odor of rotten eggs; it is heavier than air, very poisonous, corrosive, flammable, and explosive.

Formula: H2S.
Molar mass: 34.0809 g/mol.
Density: 1.36 kg/m^3.
Boiling point: -60 °C.
Melting point: -82 deg;C.
Soluble in: Water.
Classification: Sulfide, Sulfur compounds.

It is due to sulphide only.

Hydrogen sulfide is a chemical compound with the formula H2S. It is a colorless gas with the characteristic foul odor of rotten eggs; it is heavier than air, very poisonous, corrosive, flammable, and explosive.

Hydrogen sulfide often results from the bacterial breakdown of organic matter in the absence of oxygen gas, such as in swamps and sewers; this process is commonly known as anaerobic digestion H.

2S also occurs in volcanic gases, natural gas, and in some sources of well water. It is also present in natural halite type rock salts, most notably in Himalayan Black Salt, which is mostly harvested from the mineral-rich "Salt Range" mountains of Pakistan.

The human body produces small amounts of H2S and uses it as a signaling molecule.

I choose B because sulphide is a chemical which is very hot, so it heat things.

I think B is the correct answer because H2S affect both silver and brass due to chemical reaction.

I think the correct answer is option A. Because oxygen is a carrots.

Could any one reason for this answer?

I think that answer B is correct because brass is equal to Zn and Cu which is transition element. We know that such types of elements are color elements. But when brass reacts with hydrogen sulphide it becomes discolored due to the presence of air.
