Verified step by step guidance

1. Understand the Law of Conservation of Mass, which states that in a chemical reaction, the total mass of the reactants equals the total mass of the products.
2. Recognize that during a chemical reaction, such as a fire, atoms are rearranged to form new substances, but no atoms are lost or gained.
3. Apply the principle that matter cannot be created or destroyed in a chemical reaction; it only changes form.
4. Analyze the options given and identify that the correct interpretation is that matter is transformed into different substances, not destroyed or created.
5. Conclude that the mass remains constant throughout the reaction, confirming the Law of Conservation of Mass.
