The correct response to the question about how red blood cells are able to move through narrow vessels to carry oxygen throughout a multicellular organism is:
**They are small because they lack a nucleus.**
Red blood cells (erythrocytes) are uniquely structured, as they lose their nucleus during maturation, which allows more space for hemoglobin (the protein that carries oxygen) and contributes to their biconcave shape. This shape and the lack of a nucleus allow them to be more flexible, enabling them to navigate through narrow capillaries more easily.
