D. Cannot be predicted

Explanation

To determine which statement regarding the mobility of H⁺ ions in ice and liquid water is correct, we can analyze the properties of both states of water.

### Step-by-Step Solution:

1. **Understanding H⁺ Ion Mobility**:
- The mobility of an ion refers to its ability to move through a medium. In this case, we are comparing the mobility of H⁺ ions in two different states of water: ice and liquid water.

2. **Structure of Ice**:
- Ice has a crystalline structure characterized by a tetrahedral arrangement of water molecules. This structure is stable and well-organized, which affects how ions can move through it.

3. **Molecular Association in Ice vs. Liquid Water**:
- In ice, water molecules are held in a fixed position due to hydrogen bonding, creating a rigid structure. However, the tetrahedral arrangement allows for some degree of mobility for H⁺ ions.
- In liquid water, the hydrogen bonds are constantly breaking and reforming, allowing for more fluid movement of water molecules and ions.

4. **Comparing Mobilities**:
- Due to the organized structure of ice, H⁺ ions can move more freely compared to the more chaotic environment of liquid water, where the mobility is hindered by the rapid movement of water molecules and the presence of other ions.

5. **Conclusion**:
- Based on the analysis, we can conclude that the mobility of H⁺ ions in ice is greater than that in liquid water. Therefore, the correct statement is:
- **The mobility of H⁺ ions in ice is greater than that in liquid water.**

### Final Answer:
The correct statement is: **The mobility of H⁺ ions in ice is greater than that in liquid water.**
