Verified by Toppr

Global warming is the overheating of the earth due to the increased concentration of greenhouse gasses. Greenhouse gasses generally traps the radiations of the earth which leads to increase in the temperature of the earth and global warming. The greenhouse gasses includes water vapor, carbon dioxide, methane, nitrous oxide, and ozone. While the increase in the ozone whole depends on the emission of CFC.
Therefore, the correct answer is option B.
