Statement I is incorrect because the binding of carbon monoxide to haemoglobin forms carboxyhaemoglobin, which is responsible for carbon monoxide poisoning. Carbaminohaemoglobin is formed when carbon dioxide binds to haemoglobin.

Statement II is correct because carbon monoxide has an affinity for haemoglobin that is about $200$ to $250$ times greater than that of oxygen.
