Show answer
Correct Option: A
Explanation:

The air in our atmosphere is composed of molecules of different gases. The most common gases nitrogen  (78%), oxygen (about 21%), argon (almost 1%) and carbon dioxide (0.03%). Other molecules are present in  the atmosphere as well, but in very small quantities. Composition of air is measured in percent by volume,  at sea level at 15C and 101325 Pa.
