D Correct answer
Explanation

Carbon dioxide is the primary greenhouse gas responsible for the enhanced greenhouse effect and global warming. While other greenhouse gases exist (water vapor, methane, nitrous oxide), CO2 is the most significant contributor from human activities and has the greatest impact on radiative forcing. Hydrogen and fluorine are not greenhouse gases, and nitrogen dioxide is a minor contributor compared to CO2.
