The Correct Option isC
Solution and Explanation
Explanation: We can see from the curve of both the compounds:Solubility increases as temperature increase with different rate. Therefore, statement in option (C) is incorrect as it says solubility decreases with increase in temperature.Hence, the correct option is (C).
