Milk is an example of :

Options

A. true solution
B. gel
C. suspension
D. emulsion

Answer

**Step-by-Step Solution:**

1. **Identify the Composition of Milk:**
- Milk is primarily composed of water, fats, proteins, lactose, and minerals. The main component that we focus on when discussing its emulsion properties is fat.

2. **Understand the Concept of Emulsion:**
- An emulsion is a mixture of two immiscible liquids where one liquid (the dispersed phase) is dispersed in the other (the continuous phase).

3. **Determine the Type of Emulsion in Milk:**
- In the case of milk, fat globules are dispersed in water. This means that the fat is the dispersed phase and water is the continuous phase.

4. **Classify the Emulsion:**
- Since the fat is dispersed in water, milk is classified as an oil-in-water (O/W) emulsion.

5. **Conclude the Classification of Milk:**
- Therefore, milk is an example of an oil-in-water emulsion.

**Final Answer:**
Milk is an example of an oil-in-water emulsion.
