b. 78% oxygen and 21% ozone
c. 78% nitrogen and 21% oxygen
d. 78% carbon dioxide and 21% ozone
e. 78% oxygen and 21% carbon dioxide

I believe the correct answer is option C. You have just inhaled approximately 78% nitrogen and 21% nitrogen from the troposphere. The remaining 1% would be other gas impurities. This is approximately the composition of the atmosphere of the Earth which makes it a livable place.
