Explanation:

Erythrocytes are a type of blood cell. Among the given options, "red blood cells" is the correct term for erythrocytes. Hemoglobin is a protein found in red blood cells (erythrocytes) that is crucial for oxygen transport. Capillaries in the alveoli are part of the respiratory - circulatory interface but not what erythrocytes are. Oxygen molecules are carried by erythrocytes but not what erythrocytes themselves are. Soluble subunits is an incorrect description for erythrocytes.
