The correct response is: "Less energy is absorbed from the breaking of old bonds than is released from the formation of new bonds."

This is because, in an exothermic reaction, the energy released from the formation of new bonds (in the products, like water and carbon dioxide) is greater than the energy required to break the old bonds (in the reactants, like methane and oxygen). Therefore, the overall process releases energy.
