D. Aquasol

Answer

To solve the question, "When the dispersion medium is water, the colloidal sol is called:", we can follow these steps:

### Step 1: Understand the terms
- **Dispersion Medium**: This is the substance in which the dispersed particles are distributed. In this case, it is water.
- **Colloidal Sol**: This is a heterogeneous mixture where one substance (the dispersed phase) is distributed evenly throughout another substance (the dispersion medium).

### Step 2: Identify the dispersion medium
- The question specifies that the dispersion medium is water.

### Step 3: Classify the colloidal sol based on the dispersion medium
- According to the classification of colloidal solutions, when the dispersion medium is water, the colloidal sol is referred to as **Aqua Sol** or **Hydrosol**.

### Step 4: Conclusion
- Therefore, when the dispersion medium is water, the colloidal sol is called **Aqua Sol**.

### Final Answer:
When the dispersion medium is water, the colloidal sol is called **Aqua Sol**.
