Answer
Both A and R are true and R is the correct explanation of A.
Explanation — When a saturated solution is heated to a higher temperature, the solubility of most solids increases, meaning the solution can now dissolve more solid solute. So, it becomes unsaturated. Hence the assertion (A) is true. As the solution become unsaturated upon heating, more solute can be dissolved in this solution now. Hence the reason (R) is true and it is correct explanation for assertion (A).
