Answer & Solution

Answer: (Detailed Solution Below)

Option C: Carbon monoxide

Detailed Solution:

The correct answer is “Carbon monoxide”.
The air pollutant that dissolves in hemoglobin of the blood more rapidly than oxygen is carbon monoxide.

Carbon monoxide has a higher affinity for hemoglobin than oxygen, forming a stable compound called carboxyhemoglobin. This reduces the oxygen-carrying capacity of the blood, leading to a decreased supply of oxygen to the body's tissues.
