Answer

Answer:

A. chlorine atom (Cl) breaks apart the ozone molecule

Brief Explanations:

When CFCs reach the stratosphere, UV - light breaks them down, releasing chlorine atoms. These chlorine atoms react with ozone ($O_3$), breaking it into oxygen ($O_2$) and a single oxygen atom, thus depleting ozone.
