Solution

The correct option is B Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion.
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.
Therefore, the correct answer is option B.
