Vedclass · Answer

(C) Smoking tobacco releases carbon monoxide $(CO)$ into the blood. Carbon monoxide has a much higher affinity for hemoglobin $(Hb)$ than oxygen $(O_2)$. It binds with hemoglobin to form carboxyhemoglobin,which is a stable compound. This reduces the oxygen-carrying capacity of the blood,leading to a decrease in the amount of $O_2$ bound to $Hb$ and an increase in $CO$ levels in the blood.
