The combustion of gasoline.
Reason: combustion is a chemical (oxidation) reaction that releases heat and light (exothermic). The other choices absorb heat overall: baking requires heat input (endothermic overall), evaporation absorbs heat (physical, endothermic), and typical cold packs work by an endothermic dissolution.
