b. hemoglobin.
Hemoglobin is a protein that carries oxygen and is found in the blood of most animals.
It is synthesized by and is contained within erythrocytes (red blood cells).
Oxygen is bound reversibly to the iron portion.
Hemoglobin increases the oxygen-carry capacity of the blood by 70 times. 95% of the oxygen is transported by hemoglobin, 5% in blood plasma.
The bright red color occurs when it is bound with oxygen.

Hemoglobin (is a metalloprotein,a protein that contains a metal and it is a third of the total red blood cell volume) this protein is responsible for the transport of more than 98% of the oxygen (2% by blood plasma). The red blood cells of an average adult human male store collectively about 2.5 grams of iron. Hemoglobin is composed of four iron-containing ring structures (4 hemes) chemically bonded to a large protein (globin). Each iron atom can bind and then release an oxygen molecule, and each time this happens the protein changes shape so that it can bind more oxygen molecules more effectively, this is known as cooperativity. Enough hemoglobin is present in normal human blood to permit transport of about 0.2 millilitre of oxygen per millilitre of blood. The quantity of oxygen bound to hemoglobin is dependent on the partial pressure of oxygen ... (100 of 16,033 words)

Haemoglobin transports the oxygen by binding it to iron. This is the reason people who suffer from anemia are so tired all the time -- their low blood iron means the oxygen cells need to function properly are not being circulated in sufficient amounts.

B. Hemoglobin
Hemoglobin is the oxgen transporter in the red cells of the blood in mammals and other animals.

I would say haemoglobin, requiring the mineral, Iron, as an essential contribution to its proper function.

None of the above. It is transported in little green compressed gas cylinders. They are very small.
