Question

Green house gases are: A. CO$_2$ (Carbon dioxide) B. N$_2$ (Nitrogen) C. CH$_4$ (Methane) D. N$_2$O (Nitrous oxide) E. O$_2$ (Oxygen) Choose the correct answer from the options given below:

• A. B and E only
• B. C, D and E only
• C. A, C and D only
• D. A and D only

Hint:

Main greenhouse gases: CO$_2$, CH$_4$, N$_2$O

Answer 1

The Correct Option is C

Concept:
Greenhouse gases are those gases that trap heat in the Earth's atmosphere and contribute to global warming.

Step 1: Carbon dioxide (A)

• Major greenhouse gas
• Produced by burning fossil fuels

Step 2: Nitrogen (B)

• Does not trap heat
• Not a greenhouse gas

Step 3: Methane (C)

• Highly potent greenhouse gas
• Produced from livestock and wetlands

Step 4: Nitrous Oxide (D)

• Strong greenhouse gas
• Emitted from fertilizers

Step 5: Oxygen (E)

• Essential for life
• Not a greenhouse gas Final Conclusion: \[ \boxed{A, C, D} \]
