Here they have given the delta H value for the reaction right? It has mention that delta H is negative. \[\Delta H= \Delta H _{products} - \Delta H _{reactants}\] right? For delta H to be negative it's pretty clear that delta H products should have a lower value than delta H reactants. Remember when the delta H is negative it is an exothermic process hence this reaction is exothermic. Also in an exothermic reaction the heat is released to the environment. So the answer you gave is correct !
