Which Statement Best Describes How People Die of Carbon Monoxide

Which statement best describes how people die of carbon monoxide poisoning?

A) As the carbon dioxide content of blood increases, a phenomenon known as the Haldane effect converts the excess carbon dioxide to carbon monoxide until it reaches toxic levels.
B) Carbon monoxide is toxic because it readily picks up oxygen to produce carbon dioxide, causing acidosis and eventual death.
C) Carbon monoxide causes decompression sickness which can lead to death.
D) Carbon monoxide causes the carbamino effect where carbon dioxide is stripped of an oxygen, producing carbon monoxide.
E) Carbon monoxide is toxic because it binds more readily to hemoglobin than oxygen, thereby decreasing the oxygen carrying capacity of blood.
