Chart C is a saturated solution, indicating the solute concentration has reached its maximum capacity.
Chart C is most likely to represent a saturated solution. In this chart, the solute concentration reaches a plateau, indicating that the solution has reached its maximum capacity to dissolve the solute at the given temperature and pressure.
In contrast, the other charts (A and B) depict unsaturated solutions where more solute can still dissolve. Therefore, Chart C aligns with the characteristics of a saturated solution, showing the equilibrium between dissolution and precipitation.
