Correct Answer

A

Explanation

A chemical reaction in which the hydration energy is greater than the lattice energy is typically an endothermic reaction. This is because the process of hydration (the interaction of water molecules with ions or molecules) absorbs energy, while lattice energy (the energy released when ions come together to form a solid lattice) typically releases energy. So, when hydration energy is greater, it means more energy is required to break the lattice bonds than is released when the ions interact with water, resulting in a net input of energy into the system, thus making it an endothermic reaction.
