How solubility of manganese sulfide affected by potassium

Consider the dissolution of MnS in water (Ksp = 3.0 × 10-14).

MnS(s) + H2O(l) Mn2+(aq) + HS-(aq) + OH-(aq)

How is the solubility of manganese(II) sulfide affected by the addition of aqueous potassium hydroxide to the system?

Answer

A. The solubility will decrease.
B. The solubility will increase.
C. The pKa of H2S is needed before a reliable prediction can be made.
D. The amount of KOH added must be known before its effect can be predicted.
E. The solubility will be unchanged.
