D. Root cap `to` Region of meristematic activity `to` Region of elongation `to` Root hair `to` Region of maturation

Answer

To arrange the different parts of the root vertically from top to bottom, we will follow these steps:

1. **Identify the Parts of the Root**: The main parts of the root that we need to arrange are:
- Region of Maturation
- Region of Elongation
- Region of Meristematic Activity
- Root Cap

2. **Understand the Function of Each Part**:
- **Root Cap**: This is the protective tip of the root that helps it penetrate the soil.
- **Region of Meristematic Activity**: This is the area where new cells are produced, allowing the root to grow.
- **Region of Elongation**: In this region, the cells that have been produced in the meristematic region elongate, which contributes to the growth of the root.
- **Region of Maturation**: This is where the root hairs develop, and the cells differentiate into various types of cells.

3. **Arrange the Parts Vertically**:
- Starting from the top, the arrangement will be:
1. **Root Cap** (at the very bottom)
2. **Region of Meristematic Activity**
3. **Region of Elongation**
4. **Region of Maturation** (at the very top)

4. **Final Arrangement**:
- Top to Bottom:
- Region of Maturation
- Region of Elongation
- Region of Meristematic Activity
- Root Cap

5. **Conclusion**: The correct vertical arrangement from top to bottom is:
- Region of Maturation
- Region of Elongation
- Region of Meristematic Activity
- Root Cap
