Ozone has three oxygen atoms.

Explanation:
In chemistry, what matters here is how many atoms are in a single molecule. Ozone is a triatomic molecule, meaning it is made up of three oxygen atoms bonded together. Its chemical formula is O3, so one ozone molecule contains three oxygen atoms. This is different from the common form of oxygen gas, which is O2 and has only two oxygen atoms per molecule. So the statement that ozone has three oxygen atoms is correct. The option about four oxygen atoms would contradict the known formula O3, and options like “Not sure” don’t apply to well-established facts.
