Answer

Brief Explanations:

Stratospheric ozone is formed when a single oxygen atom (O) combines with an oxygen - molecule (O2). Chlorine atoms break down ozone. Combining two single oxygen atoms forms an oxygen molecule, and breaking apart an oxygen molecule doesn't form ozone.

Answer:

B. combining a single oxygen atom (O) with an oxygen molecule (O2)
