Answer: 3. The carboxyhaemoglobin (haemoglobin bound to CO) is less stable than oxyhaemoglobin.

CO binds to haemoglobin to form carboxyhaemoglobin, which cuts the oxygen-carrying capacity of blood. It is formed by incomplete combustion.

The binding of CO to haemoglobin is about 200-300 times stronger than that of \(\mathrm{O_2}\), so carboxyhaemoglobin is more stable than oxyhaemoglobin. Statement (3) says the opposite, so it is the incorrect one.
