Vedclass · Answer

(C) Carbon monoxide $(CO)$ is a highly poisonous gas. It binds to haemoglobin with an affinity approximately $200$ to $250$ times greater than that of oxygen,forming a stable compound called carboxyhaemoglobin $(COHb)$.When the concentration of carboxyhaemoglobin in the blood reaches approximately $0.30$ to $0.40 \%$,the oxygen-carrying capacity of the blood is drastically reduced.This leads to severe hypoxia in the brain,which severely impairs the functioning of the central nervous system and can eventually result in death.

If the level of carboxyhaemoglobin in blood reaches up to......,the functioning of the central nervous system is severely affected,which results in death.
