Answer: B) Structure and function relationship

Red blood cells are round, with a flat indented center without a hole. It carries oxygen and remove carbon dioxide from the body.

Red blood cells are disc shaped because they have more membrane than needed to hold the volume, so it is like a balloon that is flattened. This makes them more flexible and allow them to squeeze more easily through the capillaries. Therefore, it shows structural and functional relationship.
