Answer:
D) The exact mixture of components varies from point to point.

Additionally, the mixture that formed the air is not always the same, it variates depending on several variables, that means the air as such can slightly change is mixture, at some points can have a bit more oxygen or a bit more carbon dioxide. In other words, the air is not a constant mixture.
Having said that, the right answer is D, because the mixture of components can actually vary from point to point.
