Given below are two statements: One is lebelled as Assertion A and the other is labelled as Reason R.
Assertion A: The average composition of atmosphere near the surface of the earth is approximately 78.08% of N2, 20.95% of O2, 0.93% of Ar, 0.04% of CO2, adds to nearly 100%.
Reason R: Water content in atmosphere is variable ranging from <0.5% to 3.5% therefore, the average composition is given on dry weight percent basis (mixing ratio).
In the light of the above statements, choose the correct answer from the options given below:
1
Both A and R are true and R is the correct explanation of A
2
Both A and R are true but R is not the correct explanation of A
3
A is true but R is false
