Which of the following statements about carbon monoxide in the air is correct?
The incomplete combustion of fossil fuels produces it and replaces oxygen in haemoglobin
Carbon monoxide, produced by the incomplete combustion of fossil fuels, binds to haemoglobin in place of oxygen, making it dangerous to human health.
It is not harmless, not released only from natural sources, and is actually more dangerous than commonly assumed, not less dangerous than carbon dioxide.
Hence, 'The incomplete combustion of fossil fuels produces it and replaces oxygen in haemoglobin' is the correct answer.
