(B) Hemoglobin is a protein in red blood cells that carries oxygen. The iron atom at the center of the heme group in hemoglobin must be in the ferrous state $(Fe^{2+})$ to bind oxygen effectively. If the iron is oxidized to the ferric state $(Fe^{3+})$,it forms methemoglobin,which is incapable of binding oxygen.
