Which among the following is a heterogeneous mixture ?

Options

A. Soda water
B. Air
C. Milk
D. Sugar water

Explanation

To determine which among the given options is a heterogeneous mixture, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Definitions**:
- **Heterogeneous Mixture**: A mixture with a non-uniform composition where the different components can be seen and separated.
- **Homogeneous Mixture**: A mixture with a uniform composition where the different components are evenly distributed and cannot be easily separated.

2. **Analyze Each Option**:
- **Option 1: Soda Water**: Soda water is a homogeneous mixture because the carbon dioxide gas is uniformly dissolved in the water.
- **Option 2: Air**: Air is also a homogeneous mixture as it consists of different gases that are uniformly mixed.
- **Option 3: Milk**: Milk is a heterogeneous mixture because it contains fat globules that are not uniformly distributed in water. You can see the different components.
- **Option 4: Sugar Water**: Sugar water is a homogeneous mixture because the sugar is completely dissolved and uniformly distributed in the water.

3. **Identify the Heterogeneous Mixture**:
- From the analysis, the only option that is a heterogeneous mixture is **Option 3: Milk**.

### Final Answer:
The heterogeneous mixture among the options is **Milk**.
