D. All

Answer

To determine the solubility of lithium chloride, we need to analyze the nature of lithium chloride and the types of solvents available.

### Step 1: Understand the Composition of Lithium Chloride
Lithium chloride (LiCl) is composed of lithium ions (Li⁺) and chloride ions (Cl⁻). It is an ionic compound.

**Hint:** Identify the components of the compound to understand its ionic nature.

### Step 2: Identify the Nature of the Bond
In lithium chloride, there is a significant difference in electronegativity between lithium and chlorine. This leads to the formation of an ionic bond. However, the small size of the lithium ion gives it a high polarizing power, which can impart some covalent character to the bond.

**Hint:** Consider how electronegativity affects bond type and character.

### Step 3: Determine the Solubility in Different Solvents
- **Polar Solvents:** Water and deuterated water are polar solvents. Ionic compounds generally dissolve well in polar solvents due to the attraction between the ions and the polar molecules.
- **Non-Polar Solvents:** Benzene (C6H6) is a non-polar solvent. Ionic compounds typically do not dissolve well in non-polar solvents.

**Hint:** Recall the principle "like dissolves like" to evaluate solubility in different types of solvents.

### Step 4: Conclusion on Solubility
Given that lithium chloride is an ionic compound, it is expected to be highly soluble in polar solvents like water and deuterated water. Therefore, lithium chloride is highly soluble in water.

**Hint:** Summarize your findings based on the nature of the compound and the characteristics of the solvents.

### Final Answer
Lithium chloride is highly soluble in water.
