"gives cells the oxygen required for making energy" is correct.

Internal respiration is the exchange of gases between blood and body cells: O2 diffuses from capillaries into cells where it is used in the mitochondria to make ATP (cellular respiration), and CO2 produced by cells diffuses into the blood to be carried away. The other choices are incorrect: energy is not created inside red blood cells (they lack mitochondria), CO2 is a waste product not a fuel, and internal respiration does not remove energy.
