The observation that most likely indicates that only a chemical change has taken place is:
**A reaction occurs.**
This is because a chemical change typically involves the transformation of substances and the formation of new substances, which is characterized by a reaction. The other observations, such as changes in shape or states of matter, could also be indicative of physical changes rather than chemical changes.
