B. any two liquids
C. any two gases
D. two immiscible liquids.

Explanation

To answer the question "An emulsion is a colloidal solution formed by mixing," we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Emulsions**:
- An emulsion is a type of colloidal solution.
- Colloidal solutions consist of small particles dispersed throughout a medium.

2. **Identifying Components**:
- Emulsions are specifically formed by mixing two immiscible liquids.
- Immiscible liquids are those that do not mix together, such as oil and water.

3. **Common Example**:
- A common example of an emulsion is the mixture of liquid fat (like oil) in water.
- This is often seen in products like mayonnaise or salad dressings.

4. **Conclusion**:
- Therefore, we can conclude that an emulsion is a colloidal solution formed by mixing liquid fat (oil) with water.

### Final Answer:
An emulsion is a colloidal solution formed by mixing liquid fat in water.
