Which out of the following is a homogeneous mixture?

Options

A. milk
B. steel
C. smoke
D. soil

Explanation

To determine which of the following is a homogeneous mixture, we need to understand the definitions and characteristics of homogeneous and heterogeneous mixtures.

### Step-by-Step Solution:

1. **Understand the Definitions**:
- **Homogeneous Mixture**: A mixture that has a uniform composition throughout. The components are evenly distributed and cannot be easily distinguished from one another. Examples include solutions like saltwater, air, and alloys like steel.
- **Heterogeneous Mixture**: A mixture that does not have a uniform composition. The different components can be easily distinguished and separated. Examples include salad, soil, and oil and water mixtures.

2. **Analyze the Options**:
- If the question provides specific options, evaluate each one based on the definitions above.
- Identify if the mixture has a uniform composition or if it shows distinct layers or components.

3. **Identify the Correct Answer**:
- Based on the analysis, select the option that represents a homogeneous mixture. For example, if one of the options is "steel," it is a homogeneous mixture because it has a uniform composition of iron and carbon.

4. **Conclusion**:
- State the correct answer clearly. For example, "Steel is a homogeneous mixture because it has a uniform composition of its components."
