An reaction that releases energy into the environment.

The enthalpy change (energy taken in for bond breaking of reactants - energy released for bond forming of products) can be used to determine whether a reaction is exothermic or endothermic. Since an exothermic reaction has a negative enthalpy change, it means it releases more energy than what it takes in. Hence the third statement is correct.
