An “ozone hole” is
A)   a region centered on the equator where ozone levels are always very low because of destruction by the direct sunlight received there.
B)   a region of the stratosphere above the South Pole where ozone levels occasionally drop to very low levels.
C)   the name given to small pits or holes on the aluminum surface of an aircraft, etched there by the corrosive ozone encountered in the stratosphere, requiring regular maintenance.
D)   a permanent region of very low ozone content in the stratosphere centered over the south pole that has been there for thousands of years, the resulting transparency to UV radiation accounting for the lack of life forms there.
