Answer

Brief Explanations:

Ozone ((O_3)) formation occurs when an individual oxygen atom ((O)) combines with an oxygen molecule ((O_2)). The chemical reaction is (O + O_2\rightarrow O_3).

  • Option a: Two oxygen molecules ((O_2 + O_2)) do not form ozone.
  • Option c: Ultraviolet radiation breaks apart oxygen molecules ((O_2)) into oxygen atoms ((O)), but the key step for ozone formation is the combination of (O) and (O_2), not breaking apart four (O_2) molecules.
  • Option d: Breaking oxygen molecules into separate atoms is a preliminary step (due to UV radiation), but alone does not form ozone.

Answer:

B. an individual oxygen atom combines with an oxygen molecule
