Show answer & explanation
Correct answer: B
Global Warming Potential (GWP) measures how much heat a greenhouse gas traps in the atmosphere relative to carbon dioxide. Carbon dioxide (CO2) is the baseline with a GWP of 1. Methane (CH4) has a GWP of approximately 28-36 over 100 years. Nitrous oxide (N2O) is significantly higher at around 265. CFC-11 has a GWP exceeding 4000, and Sulfur Hexafluoride (SF6) is the most potent with a GWP of approximately 23,500. Arranging these in ascending order gives: CO2 < CH4 < N2O < CFC-11 < SF6.
