Arrange the following in correct sequence from root tip.
A) Region of maturation
B) Region of meristematic activity
C) Region of elongation
D) Root hair zone

Options

A. C A B D
B. B A C D
C. B C D A
D. C A D B

Answer

To arrange the given regions of the root in the correct sequence from the root tip, we need to understand the structure and function of each region. Here’s the step-by-step solution:

1. **Identify the Regions**: The regions we need to arrange are:
- A) Region of maturation
- B) Region of meristematic activity
- C) Region of elongation
- D) Root hair zone

2. **Understand the Functions**:
- **Region of Meristematic Activity (B)**: This is the growing point of the root where new cells are produced. It is located at the tip of the root.
- **Region of Elongation (C)**: This region is where the newly formed cells from the meristematic region elongate. It is located just above the meristematic region.
- **Root Hair Zone (D)**: This zone is where root hairs develop, which helps in the absorption of water and nutrients. It is typically found in the region of maturation.
- **Region of Maturation (A)**: This is where the cells differentiate and mature, forming the bulk of the root. It is located above the root hair zone.

3. **Sequence the Regions**: Based on the understanding of their positions:
- Starting from the tip of the root, the first region is the **Region of Meristematic Activity (B)**.
- Next is the **Region of Elongation (C)**.
- Following that is the **Root Hair Zone (D)**, which is part of the maturation process.
- Finally, the last region is the **Region of Maturation (A)**.

4. **Final Arrangement**: Therefore, the correct sequence from the root tip is:
- B (Region of meristematic activity)
- C (Region of elongation)
- D (Root hair zone)
- A (Region of maturation)

### Final Answer:
The correct sequence from the root tip is: **B, C, D, A**.
