A)nitrogen,argon,oxygen,xenon,carbon dioxide

D)oxygen,nitrogen,neon,hydrocarbons,carbon dioxide
E)carbon dioxide,oxygen,nitrogen,argon

Question

Nitrogen and oxygen are the most abundant gases in the homosphere, making up approximately 99% of the total volume. Argon is the third most abundant gas, followed by carbon dioxide and trace gases. Xenon is present in such small quantities that it is considered a trace gas and not included in the primary composition of the homosphere. Ozone and PAN are not major components of the homosphere, and neon and hydrocarbons are present at trace levels. Carbon dioxide is not as abundant as nitrogen and oxygen, and therefore is listed after them in the correct sequence.
