Options

A. Onion : Bulb, lmbricate aestivation, Axile placentation
B. Maize : `C_(3)` pathway, Closed vascular bundles, Scutellum
C. Pea : `C_(3)` pathway, Endospermic, seed, Vexillary aestivation
D. Tomato : Twisted aestivation, Axile placentation, Berry

Answer

To answer the question "Which one of the following organisms is correctly matched with its three characteristics?", we will analyze the options provided and determine which organism has the correct characteristics associated with it.

### Step-by-Step Solution:

1. **Identify the Organisms**: We need to look at the organisms listed in the options (not provided here) and their respective characteristics.

2. **Analyze Each Option**:
- **Onion**:
- **Characteristic 1**: It is a bulb.
- **Characteristic 2**: It is a modification of its stem.
- **Characteristic 3**: The type of estivation is imbricate.
- **Conclusion**: All three characteristics are correct for onion.

- **Maize**:
- **Characteristic 1**: It has a C3 pathway (Incorrect, it has a C4 pathway).
- **Characteristic 2**: Vascular bundles are open (Correct).
- **Characteristic 3**: (Not specified in the transcript).
- **Conclusion**: At least one characteristic is incorrect.

- **Pea**:
- **Characteristic 1**: It has a C3 pathway (Correct).
- **Characteristic 2**: Vexillary estivation (Correct).
- **Characteristic 3**: Endospermic seeds (Incorrect, they are non-endospermic).
- **Conclusion**: At least one characteristic is incorrect.

- **Tomato**:
- **Characteristic 1**: Twisted estivation (Incorrect, it has valvet estivation).
- **Characteristic 2**: Exile placentation (Correct).
- **Characteristic 3**: Fruit is a berry or capsule (Correct).
- **Conclusion**: At least one characteristic is incorrect.

3. **Determine the Correct Match**: Based on the analysis, the only organism that is correctly matched with its three characteristics is the **Onion**.

### Final Answer:
The correct answer is **Onion**, as it is a bulb, a modification of its stem, and has imbricate estivation.
