Answer:
A) The rearrangement of atoms is a chemical change.
Step-by-step explanation:
A chemical change is a process in which new substance (product) is formed due to a chemical reaction. Chemical reaction give rise to a chemical change can occur by simply applying heat to a substance.
In the chemical reaction symbolized, a molecule of methane reacts with two molecules of oxygen to produce carbon (IV) oxide and two molecules of water.
i.e
+2
⇒
+ 2

Thus, the relationship of the atoms shown is the rearrangement of the atoms of reactants to give new products due to a chemical reaction.
