Ring like arrangement of large number of vascular bundles is seen in

Options

A. Dicot root
B. Monocot stem
C. Dicot stem
D. Monocot root

Answer

To solve the question regarding the ring-like arrangement of a large number of vascular bundles, we will analyze the structures of the options provided: dicot root, monocot stem, dicot stem, and monocot root.

### Step-by-Step Solution:

1. **Understanding Vascular Bundles**: Vascular bundles are the part of the plant that contains xylem and phloem, which are responsible for the transport of water, nutrients, and food.

2. **Analyzing Monocot Stem**: In monocot stems, vascular bundles are scattered throughout the stem. They do not form a ring-like structure; instead, they are distributed unevenly, often found near the outer edge of the stem.

3. **Analyzing Dicot Stem**: In dicot stems, vascular bundles are arranged in a ring-like formation. This structure is characteristic of dicots and allows for efficient transport and support.

4. **Analyzing Dicot Root**: In dicot roots, the vascular bundles are arranged radially. The xylem is located at the center, surrounded by phloem, which does not form a ring structure.

5. **Analyzing Monocot Root**: In monocot roots, the vascular bundles can also be arranged in a ring, but they are fewer in number and not as distinctly organized as in dicot stems.

6. **Conclusion**: Based on the analysis, the only option that features a ring-like arrangement of a large number of vascular bundles is the dicot stem.

### Final Answer:
The correct answer is **C. Dicot Stem**.
