I apologize for any confusion earlier. The correct answer is:
C. The properties of new substances are different, so a chemical change took place.
During the combustion of hydrogen gas in the presence of oxygen, the hydrogen and oxygen atoms rearrange to form water vapor as a new substance. This process involves a chemical change, as the properties of the resulting substance (water vapor) are different from those of the individual reactants (hydrogen and oxygen gases).
