Explanation:

To solve this, we analyze each option:

• Option a: Macrocytes are enlarged red blood cells, not the main transport vehicle for gases.
• Option b: Hct (Hematocrit) is the percentage of red blood cells in blood, not a transport vehicle.
• Option c: Hgb (Hemoglobin) is a protein in red blood cells that binds to oxygen and carbon dioxide for transport.
