The correct response that indicates a release of bond energy when hydrogen gas (H2) and oxygen gas (O2) combine is **a loud popping noise**. This noise is often associated with the exothermic reaction that occurs when hydrogen combusts in the presence of oxygen, indicating that energy is being released.
