Why can a small amount of chlorine released from an ozone-depleting substance cause substantial ozone destruction?

A
A released chlorine atom can participate in many ozone-destroying reactions.
B
Chlorine is permanently consumed in a single reaction with ozone.
C
Chlorine blocks UV-B before it reaches the stratosphere.
D
Chlorine converts ground-level ozone into stratospheric ozone.

An HFC refrigerant contains no chlorine and has little ozone-depletion potential, but its global-warming potential is high. What conclusion follows?

A
A low ODP means the refrigerant cannot affect climate.
B
The refrigerant may have little or no ODP but still trap substantial heat.
C
A high GWP means the refrigerant must contain chlorine.
D
HFCs affect climate only by damaging the ozone layer.
