Can someone explain why the answer was O2. All I remember from the passage was that it was “air” that they said did whatever it did (haha I really dont remember it at all) and I ended up choosing N2 (studying for chem sat2 I remembered that nitrogen was the major component of air lol)… so any explaining to why its O2 would be great
