Which statement about GWP values is true?

Explanation:
Global Warming Potential shows how much heat a refrigerant traps in the atmosphere over a set time (usually 100 years) compared with CO2. A higher GWP means a greater potential to contribute to warming. R-12 (CFC-12) has a very high GWP—roughly around 10,000—much higher than R-410A (a blend of HFCs), which is about 1,800–2,200. Because of that, R-12 has the highest GWP among these options. So the statement about R-12 having the highest GWP is true. The other claims aren’t correct: R-12 does not have a lower GWP than R-410A; halons aren’t the only refrigerants with GWP values; and GWP is indeed a concern when selecting refrigerants.
