Correct answer: C. Oxygen content
- A. Caking power
- B. Calorific value
- C. Oxygen content
- D. Hydrogen content
Explanation
Low-temperature oxidation consumes combustible constituents and lowers caking power, hydrogen content and calorific value. Since oxidation adds oxygen-containing groups, the oxygen content does not decrease.
