Which statement best distinguishes the environmental concerns associated with CFCs, HCFCs, and many HFCs?

  1. A

    CFCs, HCFCs, and HFCs all deplete ozone to the same extent.

  2. B

    CFCs and HCFCs can deplete ozone, while many HFCs do not deplete ozone but have high global-warming potential.

  3. C

    HFCs deplete ozone, but CFCs and HCFCs do not affect the climate.

  4. D

    Only refrigerants that deplete ozone can contribute to climate warming.
