Nitrogen obtained from air is not absolutely pure because it contains the following except
Nitrogen obtained from air is generally considered "impure" compared to chemically synthesized nitrogen because it contains trace amounts of atmospheric constituents that are difficult to separate entirely.
Carbon (IV) oxide (CO₂) is the correct answer because it is typically removed early in the industrial process of separating nitrogen from air (such as passing air through caustic soda/sodium hydroxide). Therefore, the final nitrogen obtained is considered to no longer contain CO₂.
