Solution

The correct option is B
Carbon monoxide

The patient has inhaled polluted air containing a high content of carbon monoxide. Carbon monoxide combines more readily with haemoglobin than oxygen. It forms a stable compound, carboxyhaemoglobin, which reduces the amount of free haemoglobin available for carrying oxygen and starves the tissues of oxygen. Deficiency of oxygen causes headache, dizziness, nausea, paralysis and even death.
