A) carbon dioxide and water vapour ✓
B) nitrogen and water vapour.
C) oxygen and carbon dioxide.
D) oxygen and nitrogen..
Explanation:-
Breathing involves exchange of gases which is composed of air with variable composition of gases.
In breathed in air, there is 21% of oxygen and breathed out air contains only 16% oxygen.
In breathed in air, there is 0.04% of carbon dioxide and breadthed out air contains 4% carbon dioxide.
Hence, the relative amount of oxygen is less and carbon dioxide is more. As per the question, Compared with the air she breathes out, the air she breathes in contains less CO2 and water vapour.
