Answer: Option C) blocks oxygen transport in human blood
Explanation:
Carbon monoxide (CO) is one of the oxides of carbon formed when fuel is incompletely burned. It can be generated from exhaust pipe of vehicles, electric generators.
When inhaled CO attaches to the hemoglobin portion of the red blood cells, forming a bound complex called CARBOXY-HEMOGLOBIN, that is unable to transport oxygen to the body tissues.
Thus, by this mechanism Carbon monoxide blocks oxygen transport in human blood
