Which one is an example of miceller system?

Options

A. Soap + water
B. Rubber + benzene
C. Protein + water
D. None of these

Answer

To determine which option is an example of a micellar system, we need to analyze the provided options based on the characteristics of micelles and colloidal systems.

### Step-by-Step Solution:

1. **Understanding Micellar Systems**:
- Micelles are aggregates of surfactant molecules that form in solution when the concentration of surfactants exceeds a certain threshold known as the critical micelle concentration (CMC). They have a hydrophobic core and a hydrophilic exterior.

2. **Analyzing the Options**:
- **Option 1: Soap + Water**:
- Soap is a surfactant. When soap is added to water, it can form micelles at concentrations above the CMC. Thus, this is a clear example of a micellar system.

- **Option 2: Rubber + Benzene**:
- This combination does not form micelles. Rubber is a macromolecule and does not behave like a surfactant in this context. Therefore, this option is not correct.

- **Option 3: Protein + Water**:
- While proteins can form colloidal solutions, they do not specifically form micelles like surfactants do. Hence, this option does not qualify as a micellar system.

- **Option 4: Not provided in the transcript**:
- Since we have no information about this option, we cannot evaluate it.

3. **Conclusion**:
- Based on the analysis, **Option 1 (Soap + Water)** is the correct answer as it is an example of a micellar system.

### Final Answer:
**The example of a micellar system is Soap + Water.**
