The correct answer is:
B. The reactants have more total bond energy than the products.
In a combustion reaction, such as that of a burning match, the reactants (in this case, primarily the chemicals in the match head and oxygen from the air) contain more total bond energy compared to the products (which are typically gases such as carbon dioxide and water). During the combustion process, energy is released as bonds are broken in the reactants and new bonds are formed in the products, which results in the overall system releasing energy (in the form of heat and light). Therefore, the total bond energy of the reactants is greater than that of the products.
