Only Tanu is correct: "We inhale air rich in oxygen."
Explanation
Anu's statement
("We inhale air") is too vague. Air is a mixture of gases including oxygen, nitrogen, and others. Saying just "air" does not capture what is important about what we breathe in.
Shanu's statement
("We inhale oxygen") is wrong. We do not inhale pure oxygen — we inhale air, which contains about 21% oxygen along with nitrogen and other gases.
Tanu's statement
("We inhale air rich in oxygen") is correct and most precise. Air is approximately 21% oxygen — it is rich in oxygen, not pure oxygen.
We inhale air (a mixture), not pure oxygen. The air we breathe in is rich in oxygen (~21%). Tanu is the most accurate.
