A
to carry iron
B
to carry wastes
C
to carry oxygen
D
to produce oxygen
Explanation: 

Detailed explanation-1: -Hemoglobin is a two-way respiratory carrier, transporting oxygen from the lungs to the tissues and facilitating the return transport of carbon dioxide. In the arterial circulation, hemoglobin has a high affinity for oxygen and a low affinity for carbon dioxide, organic phosphates, and hydrogen and chloride ions.

Detailed explanation-2: -The main function of hemoglobin is to carry oxygen to different tissues of the body for energy metabolism, and then transport carbon dioxide back to the lungs. It can also scavenge nitric oxide [101].

Detailed explanation-3: -Red blood cells and haemoglobin The red blood cells contain a pigment called haemoglobin, each molecule of which binds four oxygen molecules. Oxyhaemoglobin forms. The oxygen molecules are carried to individual cells in the body tissue where they are released. The binding of oxygen is a reversible reaction.
