- It always increases with increase in temperature.
- It always decreases with increase in temperature.
- It may increase or decrease depending on the enthalpy change.
- It does not depend on temperature.

The Correct Option is C
Solution and Explanation
The solubility of a solid in a liquid is influenced by the enthalpy change of the dissolution process. If the process is endothermic (absorbs heat), solubility increases with temperature. If the process is exothermic (releases heat), solubility decreases with temperature. Hence, there is no general rule, and it depends on the nature of the solute and solvent interaction.
