The last statement i.e., if exposed to air free heme group ( not associated with hemoglobin) is readily oxidized converting Fe2+to Fe3+ and can no longer bind oxygen. - this statement is false.
so the correct option is option D.

Which five statements about hemoglobin and myoglobin structure are true? Both hemoglobin and myoglobin contain a prosthetic group called heme, which contains a central iron atom. Each iron atom can form six coordination bonds. One of these bonds is formed between iron and oxygen. Heme is composed of an organic protoporphyrin component and a metal atom. By itself, heme is not a good oxygen carrier. It must be part of a larger protein to prevent oxidation of the iron atom....

Which five statements about hemoglobin and myoglobin structure are true? Each iron atom can form six coordination bonds. Two of these bonds are formed between iron and oxygen. Each hemoglobin or myoglobin molecule can bind four oxygen molecules. Heme is composed of an organic protoporphyrin component and a metal atom. Hemoglobin is a heterotetramer, whereas myoglobin is a monomer. By itself, heme is not a good oxygen carrier. It must be part of a larger protein to prevent oxidation of...

Question 8 1 pts Why is it important that the heme prosthetic group be buried in a hydrophobic pocket in Oz-binding proteins? The heme iron is readily oxidized to Fe3+, which cannot bind 02. The heme group is entirely hydrophobic and therefore cannot be solvent exposed. 02 is uncharged and hydrophobic and therefore needs this type of environment in order to bind. The heme group would bind H2O instead of O2 if it were solvent exposed.
