Given the following solubility constants, which list arranges the solutes in order of increasing solubility?

Question

CaCO3: Ksp = 2.8 × 10-9
Ca(OH)2: Ksp = 5.5 × 10-6
CaSO4: Ksp = 9.1 × 10-6
CaF2: Ksp = 5.3 × 10-9

A. CaSO4 < Ca(OH)2 < CaCO3 < CaF2
B. CaSO4 < Ca(OH)2 < CaF2 < CaCO3
C. CaCO3 < CaF2 < Ca(OH)2 < CaSO4
D. CaF2 < CaCO3 < Ca(OH)2 < CaSO4
