The chart shows that nitrogen makes up the majority of air (78%), while oxygen, argon, and carbon dioxide are present in much smaller amounts. This indicates that nitrogen is the solvent, while the other gases are solutes. Therefore, the best choice is C, which correctly identifies oxygen, argon, and carbon dioxide as solutes and nitrogen as the solvent.
