The correct response is:
It shows that no atoms have been gained or lost during the reaction.
This statement highlights that the total number of atoms of each element on the reactant side of the equation (2 Fe, 6 O, and 3 C) is equal to the total number of atoms on the product side (4 Fe, 3 CO₂), thus demonstrating the Law of Conservation of Mass, which states that mass (and thus the number of atoms) must be conserved in a chemical reaction.
