The solubility product (\( K_{\text{sp}} \)) of a sparingly soluble salt \( \text{A}_2\text{X}_3 \) is \( 1.08 \times 10^{-23} \). Its molar solubility (\( S \)) in pure water is:

1. A
   \( 1.0 \times 10^{-5} \text{ mol L}^{-1} \)
2. B
   \( 1.0 \times 10^{-4} \text{ mol L}^{-1} \)
3. C
   \( 2.0 \times 10^{-5} \text{ mol L}^{-1} \)
4. D
   \( 1.0 \times 10^{-6} \text{ mol L}^{-1} \)
