Which of the following shows a correct difference between monocots and dicots ?

Options

A. `{:("Character ","Dicotyledon","Monocotyledon"),("Venation","Parallel venation ","Reticulate venation"):}`
B. `{:("Character ","Dicotyledon","Monocotyledon"),("Flower ","Trimerous ","Tetramerous or pentamerous"):}`
C. `{:("Character ","Dicotyledon","Monocotyledon"),("Vascular bundle ","Ringed ","Scattered"):}`
D. More than one option is correct.

Answer

To solve the question regarding the correct difference between monocots and dicots, we will analyze each option provided in the question.

### Step-by-Step Solution:

1. **Understanding Monocots and Dicots**:
- Monocots (monocotyledons) are plants that have one seed leaf (cotyledon).
- Dicots (dicotyledons) have two seed leaves (cotyledons).

2. **Analyzing the Options**:
- **Option 1**: This option states that dicots have parallel venation and monocots have reticulate venation.
- **Analysis**: This is incorrect. Dicots typically have reticulate (net-like) venation, while monocots have parallel venation.

- **Option 2**: This option claims that dicots have trimarous flowers and monocots have tetramarous and pentamarous flowers.
- **Analysis**: This is also incorrect. Dicots usually have tetramarous (four parts) or pentamarous (five parts) flowers, while monocots typically have trimarous (three parts) flowers.

- **Option 3**: This option states that in dicots, the vascular bundles are arranged in a ring, while in monocots, they are scattered.
- **Analysis**: This is correct. In dicots, vascular bundles are arranged in a ring formation, whereas in monocots, they are scattered throughout the stem.

3. **Conclusion**:
- The correct answer is **Option 3**, as it accurately describes the difference between monocots and dicots regarding the arrangement of vascular bundles.

### Final Answer:
The correct difference between monocots and dicots is that dicots have vascular bundles arranged in a ring, while monocots have them scattered.
