To determine which of the options is an example of a solid emulsion, we first need to understand what an emulsion is and the characteristics of solid emulsions.

### What is an Emulsion?

An emulsion is a mixture of two immiscible liquids, where one liquid (the dispersed phase) is dispersed in the other (the continuous phase). Emulsions can be classified into two main types:

1. **Oil-in-water (O/W)**: Where oil droplets are dispersed in water (e.g., milk).
2. **Water-in-oil (W/O)**: Where water droplets are dispersed in oil (e.g., butter).

### What is a Solid Emulsion?

A solid emulsion is a type of emulsion where the continuous phase is solid, and the dispersed phase can be either liquid or solid. Solid emulsions often have a creamy or spreadable texture and are typically found in products like margarine and butter.

### Analyzing the Options

Now, let's analyze each of the options provided:

**A. Butter**
- Butter is a classic example of a water-in-oil emulsion. It consists of fat (the continuous phase) and water (the dispersed phase). When butter is chilled, it becomes solid, making it a solid emulsion. Therefore, butter is a solid emulsion.

**B. Hair cream**
- Hair cream is typically an oil-in-water emulsion, where oils are dispersed in water. While it may have a creamy texture, it is not solid at room temperature and does not fit the definition of a solid emulsion.

**C. Milk**
- Milk is an oil-in-water emulsion where fat globules are dispersed in water. It is a liquid at room temperature and does not qualify as a solid emulsion.

**D. Cod-liver oil**
- Cod-liver oil is primarily a liquid and is an oil-in-water emulsion. It does not have a solid structure and therefore cannot be classified as a solid emulsion.

### Conclusion

Based on the analysis, the only option that qualifies as a solid emulsion is:

**A. Butter**

Butter is a solid emulsion because it consists of fat (the continuous phase) and water (the dispersed phase) and is solid at room temperature.
