CFCl ₃ is responsible for the decomposition of ozone to oxygen. Which of the following reacts with ozone to form oxygen?

Step-by-step solution

CFC (Chlorofluorocarbons) are causing depletion of ozone in the stratosphere. This occurs because ultra violet light also causes CFC's to decompose, producing atomic chlorine. The chlorine atoms react with ozone molecules, resulting in a net removal of O ₃ molecules from the stratosphere.
