The role of oxygen in the atmosphere is not limited to life support because it is also necessary in which process?
Answer and explanation
Correct answer: Combustion
The governing concept is oxygen’s role as a supporter of oxidation reactions. In respiration, oxygen helps release energy from food, and in combustion it combines with a fuel during burning, usually producing heat and light. Therefore option A is correct. Condensation nuclei are generally supplied by dust, salt, or other particles, not oxygen; ozone liquefaction is a physical phase-change issue, and argon’s inertness does not require oxygen. Thus B, C, and D are distractors.
