Detailed Explanation & Answer

The correct sequence based on Global Warming Potential (GWP) from lowest to highest is:

B. CO₂ < A. CH₄ < D. N₂O < C. CFC-11

Approximate GWP values over 100 years:
CO₂ = 1
CH₄ ≈ 25–30
N₂O ≈ 265–300
CFC-11 ≈ 4600–5000

ग्लोबल वार्मिंग पोटेंशियल (GWP) के आधार पर सबसे कम से सबसे अधिक तक का सही क्रम है:

B. CO₂ < A. CH₄ < D. N₂O < C. CFC-11

100 वर्षों में अनुमानित GWP मान:

CO₂ = 1
CH₄ ≈ 25–30
N₂O ≈ 265–300
CFC-11 ≈ 4600–5000

The Correct Answer is 4
