    They are opposites because endothermic reactions require energy and exothermic reactions release energy.

    Explanation:

    Since exothermic reactions release energy in the form of heat they are characterized by the fact that the energy levels of their reagents are higher than those of their product, which means that part of the chemical energy contained in their bonds has been released in a new way.

    A chemical reaction is endothermic when it absorbs energy (heat) from the environment. In this case, heat is transferred from outside to inside the system

    therefore the correct option is They are opposites because endothermic reactions require energy and exothermic reactions release energy.
