Verified Answer
A. Nitrogen oxide
B. Carbon dioxide
C. Methane
D. Ozone
Explanation:
Carbon dioxide, Methane, and Ozone are naturally occurring greenhouse gases. Nitrogen oxide (NOx) is primarily an air pollutant, though nitrous oxide (N2O) is a greenhouse gas. However, 'Nitrogen oxide' as a general term is not considered a major natural greenhouse gas in the same way as the others.
