Solution

The correct option is B Carbaminohaemoglobin
Carbaminohaemoglobin is formed by the reversible combination of carbon dioxide and haemoglobin. It is formed at the cellular level in the presence of low partial pressure of oxygen and low acidic haemoglobin. It dissociates at the lung level where conditions are opposite i.e. high partial pressure of oxygen.

Carboxyhaemoglobin results due to the binding of carbon monoxide with haemoglobin.

Oxyhaemoglobin is an unstable compound formed due to the binding of oxygen with haemoglobin.
