The three air pollutants, X, Y and Z, are outlined below. X is a poisonous gas produced when an alkane undergoes incomplete combustion. Y is produced when vegetation decomposes and it adds to global warming. Z leads to breathing difficulties and acid rain. What are the identities of X, Y and Z?
- AX: carbon monoxide, Y: methane, Z: oxides of nitrogen
- BX: carbon monoxide, Y: particulates, Z: carbon dioxide
- CX: sulfur dioxide, Y: methane, Z: oxides of nitrogen
- DX: sulfur dioxide, Y: particulates, Z: carbon dioxide
