you people don't Read questions properly you just jump to conclusions and talk anyhow.
you answer questions base on the options provided.
if N2 was an option alone then it would be nitrogen.
but you are seeing N2 and O2 together as an option, knowing fully well that nitrogen, oxygen, argon and other rare elements belonging to group zero in the periodic table are also involved in the atmosphere but with a very low percentage which combined together is about 1% alone, that alone should tell you that option D which has N2 and O2 is the answer since N2 alone is not there, and those saying A can you explain? those saying the answer I not there did you see non of the above?

dear my school either give a concrete explanation why your answer is d or correct it
your chosen option is wrong and the correct answer ain't present only if you have decided to mess with our brains

%by volume; using vol./22.4×100
for co2 4/22.4×100=18
for N2 72/22.4×100=321
for O2 24/22.4×100=107
from the cal. one could conclude that N2 and O2 has the highest volume

The anwers tyou are bringing in correction does not match the options I picked.
To me,it seems you are giving me options that I did not pick during the test.
