The correct option is- The fireworks give off heat.
- An exothermic reaction is a chemical reaction in which heat is released when the reactant is converted into products. All combustion reactions are examples of exothermic reactions.
- An endothermic reaction is a chemical reaction in which energy is absorbed for the conversion of reactants to products. The melting of ice absorbs heat, hence it is an endothermic reaction.
- The ignition of fireworks releases heat into the surroundings hence, it is an exothermic reaction.
