Green house gases can be arranged in 'Global Warming Potential' sequence as

Global-warming potential (GWP) is a comparative index that shows how much heat a greenhouse gas traps in the atmosphere relative to the same mass of $$\text{CO}_2$$ over a fixed time horizon (usually 100 years). By convention, $$\text{CO}_2$$ is assigned a GWP of 1.

Typical 100-year GWP values commonly quoted in environmental chemistry are:

$$\text{CO}_2 : 1$$
$$\text{CH}_4 : 25 \text{-} 30$$ (often rounded to 28)
$$\text{N}_2\text{O} : 260 \text{-} 300$$ (often rounded to 265)
$$\text{CFCs} : 4000 \text{-} 14000$$ (value depends on the specific CFC; for example, $$\text{CFC-12}$$ ≈ 10 900)

Thus, the gases arranged in decreasing GWP are:

$$\text{CFCs} \gt \text{N}_2\text{O} \gt \text{CH}_4 \gt \text{CO}_2$$

Comparing with the given options, this sequence matches Option B.

Hence, the correct answer is:
Option B which is: $$\text{CFC} \gt \text{N}_2\text{O} \gt \text{CH}_4 \gt \text{CO}_2$$
