Explanation

To solve the question regarding the type of emulsion that butter represents, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Definition of Emulsion**:
- An emulsion is a colloidal system where both the dispersed phase and the dispersion medium are liquids.

2. **Identify the Types of Emulsions**:
- There are two main types of emulsions:
- **Oil in Water (O/W)**: Here, oil is the dispersed phase and water is the dispersion medium. Examples include milk and vanishing cream.
- **Water in Oil (W/O)**: In this case, water is the dispersed phase and oil is the dispersion medium. Examples include butter and cold cream.

3. **Analyze the Options Provided**:
- The options given are:
- Option 1: Water in Oil
- Option 2: Oil in Water
- Option 3: None
- Option 4: Not Applicable

4. **Determine the Correct Match for Butter**:
- Since butter is primarily composed of water droplets dispersed in fat (oil), it fits the definition of a water-in-oil emulsion (W/O).

5. **Select the Correct Option**:
- Based on the analysis, the correct option that matches butter is **Option 1: Water in Oil**.

### Final Answer:
The correct option is **Option 1: Water in Oil**.
