• A. carbon dioxide, methane, nitrous oxide and CFCs
• B. carbon dioxide, methane and CFCs
• C. only carbon dioxide
• D. carbon dioxide and CFCs

Answer 1

The correct option is A carbon dioxide, methane, nitrous oxide and CFCs

The greenhouse effect is a naturally occurring phenomenon that is responsible for heating of Earth’s surface and atmosphere.

Radiation from the earth's atmosphere warms the earth's surface to a higher temperature.

Green house effect is one of the major environmental issues. Enhanced greenhouse effect is mainly due to increased emission of greenhouse gases such as carbon dioxide, methane, nitrous oxide and CFCs, and also due to deforestation.

Therefore, option (a) carbon dioxide, methane, nitrous oxide and CFCs is the correct answer.
