Vedclass · Answer

(C) Carbon monoxide $(CO)$ is a poisonous gas that binds to haemoglobin to form carboxyhaemoglobin.Haemoglobin has a significantly higher affinity for $CO$ than for oxygen $(O_2)$.This affinity is approximately $200$ to $210$ times greater for $CO$ than for $O_2$.Because of this, even small concentrations of $CO$ can effectively block oxygen transport in the blood, leading to tissue hypoxia and potential death.

The toxic effect of carbon monoxide is due to its greater affinity for haemoglobin as compared to oxygen, approximately by (in $\times$)
