Which statement most accurately describes the relationship between the hydrogen ion concentration and carbon dioxide concentration in extracellular fluids?
A.   Because carbon dioxide is a gas and hydrogen ions are electrolytes, these two substances have no relationship in extracellular fluids.
B.   The concentrations of hydrogen ions and carbon dioxide are directly related, with an increase or decrease in one always resulting in a corresponding increase or decrease in the other.
C.   Carbon dioxide buffers hydrogen ions; thus, these two concentrations are inversely related to each other. The higher the carbon dioxide concentration, the fewer hydrogen ions are present in that fluid.
D.   Hydrogen ions and carbon dioxide ions exist in a balanced relationship as a result of their charges. The positively charged hydrogen ions are attracted to the negatively charged carbon dioxide ions, forming an electrically neutral substance.
