Solution
The correct option is B Haemoglobin
Haemoglobin is an iron-protein compound in red blood cells that gives blood its red colour and transports oxygen, carbon dioxide, and nitric oxide. It carries oxygen from the lungs or gills, where blood is oxygenated, to body cells. When saturated with oxygen, haemoglobin is called oxyhaemoglobin. After releasing oxygen to the body tissues, haemoglobin reverses its function and picks up some of the carbon dioxide produced as the waste product of cellular respiration, for transport to the lungs, where it is released outside by expiration. When saturated with carbon dioxide, haemoglobin is known as carbaminohaemoglobin.
