The correct response related to the provided equation \( \text{CH}_4 + 2 \text{O}_2 \rightarrow \text{CO}_2 + 2 \text{H}_2\text{O} \) is:
**A** The rearrangement of atoms is a chemical change.
This is because the reaction involves the breaking of bonds in the reactants and the formation of new bonds in the products, indicating a chemical change rather than just a physical change. Other options B, C, and D describe physical changes or concepts not directly related to the chemical reaction presented.
