Cl Atoms Formed Via Photolysis of C-Cl Bonds of Chlorofluorocarbons

Cl atoms formed via photolysis of C-Cl bonds of chlorofluorocarbons in the stratosphere are particularly effective in destroying ozone at these altitudes because ________.

A) Cl atoms absorb UV, which generate O atoms to react with O₂ to produce ozone
B) Cl atoms catalytically convert O₃ to O₂
C) Cl atoms stoichiometrically convert O₃ to O₂
D) Cl atoms react with H atoms, which catalyze conversion of O₂ to O₃
E) Cl atoms react with N atoms, which catalyze conversion of O₂ to O₃
