B. liquid ,liquid, lyophobic
C. solid,liquid,lyophobic
D. solid,liquid,lyophilic

Explanation

To solve the question regarding the dispersed phase, dispersion medium, and the nature of the colloidal solution of gold solution, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Components of the Colloidal Solution:**
- In a colloidal solution, there are two main components: the dispersed phase and the dispersion medium.
- The dispersed phase is the substance that is distributed throughout the dispersion medium.

2. **Determine the Dispersed Phase:**
- In the case of a gold solution, gold exists in a colloidal form. Here, gold particles are the dispersed phase.
- Therefore, the dispersed phase is **gold (solid)**.

3. **Determine the Dispersion Medium:**
- The dispersion medium is the liquid in which the dispersed phase is suspended.
- In a gold solution, the gold particles are suspended in a liquid (usually water or another solvent).
- Therefore, the dispersion medium is **water (liquid)**.

4. **Classify the Nature of the Colloidal Solution:**
- Colloidal solutions can be classified as lyophilic (liquid-loving) or lyophobic (liquid-hating).
- Lyophilic colloids are those that easily mix with the dispersion medium, while lyophobic colloids do not mix easily and require specific methods for preparation.
- Gold, being a metal, does not readily mix with water and is classified as a lyophobic colloid.
- Therefore, the nature of the colloidal solution is **lyophobic**.

### Final Answer:
- The dispersed phase is **gold (solid)**.
- The dispersion medium is **water (liquid)**.
- The nature of the colloidal solution is **lyophobic**.
