The solubility of hydroxides of group 2 elements increases on moving down the group.$\mathrm{B}\mathrm{e}(\mathrm{O}\mathrm{H}{)}_2$has minimum solubility in water. The lesser the solubility of the hydroxides, the smaller will be is solubility product. Hence,$\mathrm{B}\mathrm{e}(\mathrm{O}\mathrm{H}{)}_2$has the lowest solubility product amongst the group 2 hydroxides.
