The correct option is this: WHEN THE ENTHALPY CHANGE OF THE REACTION IS POSITIVE, THE REACTION IS ENDOTHERMIC.

A chemical reaction can be an exothermic reaction or an endothermic reaction based on whether it absorb or give out energy when it is occurring. An exothermic reaction is a type of reaction that gives out energy when it is occurring. The enthalpy change of exothermic reactions is always negative. An endothermic reaction is a type of chemical reaction in which energy is absorbed from the environment. The enthalpy change of endothermic reaction is always positive.
