• D. Both statements are incorrect.

Answer 1

The correct option is C

Statement (i) is correct and statement (ii) is incorrect.

Carbon monoxide is a harmful air pollutant. It combines with haemoglobin in the human body and forms carboxyhaemoglobin. This reduces the oxygen absorption capacity of the blood. If the carbon monoxide level is too high then the person will feel too unconscious and die.
