Which statement best describes an HFC

Multiple choice — select the best answer

AContains chlorine and depletes ozone
BContains no chlorine and has zero ozone-depletion potential
CIs a natural refrigerant with no global-warming impact
DIs identical to a CFC

✓ Correct answer: B. Contains no chlorine and has zero ozone-depletion potential HFCs (hydrofluorocarbons) contain no chlorine, so their ozone-depletion potential is zero. They do, however, have a global-warming potential, which is why their use is also being managed.
