Which of the following best describes the effects of using
hydrofluorocarbons (HFCs) or hydrochlorofluorocarbons
(CFCs) to replace chlorofluorocarbons (CFCs) in industrial
processes?
while HFCs and HCFCs are less likely to deplete stratospheric ozone, they
contribute more to global warming than CFCs do
while HFCs and HCFCs are more likely to deplete stratospheric ozone, they contribute
less to global warming than CFCs do
HFCs and HCFCs are more likely to deplete stratospheric ozone and contribute less
to global warming than CFCs do
HFCs and HCFCs are less likely to deplete stratospheric ozone and contribute less
to global warming than CFCs do
there is no difference between HFCS, HCFCS, CFCs in terms of stratospheric ozone
depleting and global warming effects

Answer:

Option D, HFCs and HCFCs are less likely to deplete stratospheric ozone and contribute less  to global warming than CFCs do

Explanation:

HFCs have the ability to replace CFCs. They are able to deplete the stratospheric ozone because they have chlorine. However, their ozone depletion potentials (ODPs) is quite less as compared to that of CFCs. HCFCs ozone depletion potentials (ODPs) is between 0.01 to 0.1 while that of CFCs is around 1. Hence, HCFCs deplete less  stratospheric ozone and hence their contribution to global warming is comparatively low

Hence, option D is correct

O The crude birthrate remains higher than the crude death rate.
O The crude birthrate declines faster than the crude death rate.
O Economic changes stabilize the crude death rate.
O Economic changes stabilize the crude birthrate.
