When Kip > Ksp, then solution is supersaturated and precipitation takes place. Therefore, Option C is the correct answer.
Explanation: No precipitation of the electrolyte occurs if the ionic product is less than the solubility product, i.e., the solution has not reached the saturation stage.
Case I: When Kip<Ksp, then solution is unsaturated in which more solute can be dissolved.
Case II: When Kip = Ksp, then solution is saturated in which no more solute can be dissolved.
Case III: When Kip > Ksp, then solution is supersaturated and precipitation takes place.
