### Answer: Capillary Walls Composition

Capillary walls are primarily composed of **simple squamous epithelium**. This thin layer of flat cells allows for efficient exchange of gases and nutrients between the blood and surrounding tissues. The structure of simple squamous epithelium facilitates this process due to its minimal thickness, providing a barrier that is both permeable and efficient for diffusion.

### Explanation of Options
1. **Areolar Connective Tissue**: This type of tissue serves as a loose connective framework, but it is not the primary component of capillary walls.
2. **Simple Squamous Epithelium**: This is indeed the correct answer, as capillaries consist of a single layer of endothelial cells that are simple squamous in shape.
3. **Stratified Squamous Epithelium**: This type of epithelium consists of multiple layers of cells and is found in areas requiring protection, such as the skin, but not in capillaries.
4. **Smooth Muscle**: While smooth muscle is important for regulating the diameter of blood vessels, it is not present in capillary walls.

### Final Answer
**Simple Squamous Epithelium** is the correct choice.
