The observation that most likely indicates that only a chemical change has taken place is **“The change cannot be reversed.”**
This is because chemical changes often result in the formation of new substances that cannot easily be converted back to their original forms, whereas physical changes (like shape changes and states of matter changes) can typically be reversed.
