What is the most correct basis for calling nitrogen and oxygen the major gases of dry air?
Answer and explanation
Correct answer: Together they make up most of the volume of dry air
The governing basis for describing gases as major components is their proportion by volume in dry air. Nitrogen forms the largest share and oxygen forms the second-largest share; together they account for nearly all of dry air, apart from small quantities of other gases. Therefore option B is correct. Colour, seasonal occurrence, and classification as dust particles are not valid criteria for identifying major gases.
