Solution
The correct option is C Carbon monoxide When a patient is exposed to high concentrations of carbon monoxide, the haemoglobin in the body has a higher affinity to carbon monoxide than oxygen. So Hb starts forming a complex with carbon monoxide called carboxyhaemoglobin. Thus, carbon monoxide is the right answer.
