The given expression K_sp = 4s³ is the solubility product expression for the ionic compound formed by cation C and anion A. It is given that s is the molar solubility of the ionic compound. In order for the ionic compound to form in an aqueous solution, the concentrations of cation C and anion A must exceed the solubility product constant, K_sp, such that precipitation can occur. From the given expression, we can see that the product of the concentrations of cation C and anion A is directly proportional to the molar solubility of the ionic compound, s. Therefore, we can conclude that the concentration of cation C or anion A alone is not sufficient for precipitation to occur, but it is the product of their concentrations that matters. Looking at the figures, we can see that both I and II represent aqueous solutions containing either cation C or anion A alone, and hence, precipitation will not occur in these cases. Figure III, on the other hand, represents the mixing of aqueous solutions containing both cation C and anion A, which can result in precipitation if their concentrations exceed the solubility product constant, K_sp, as given in the solubility product expression. Therefore, the possible result of the mixing of aqueous solutions containing cation C and anion A is represented by Figure III, and hence, the correct answer is C.
