o both the absorption and release of energy depending on the type of reaction
o only the release of energy
o only the absorption of energy
o neither the absorption or release of energy

Explanation:

In chemical reactions, energy changes occur. Endothermic reactions absorb energy, while exothermic reactions release energy. So, depending on the type of reaction, both absorption and release of energy can happen.
