Which one of the following organisms is correctly matched with its three characteristics

Options

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

Explanation

To solve the question of which organism is correctly matched with its three characteristics, we can follow these steps:

### Step 1: Analyze the Organisms and Their Characteristics
We need to look at each organism and its associated characteristics to determine if they are correctly matched.

### Step 2: Evaluate Each Option
1. **P (Plant)**:
- Dark reaction: T3 pathway (incorrect, it should be C3 pathway)
- Seeds: Non-endospermic (incorrect, they are endospermic)
- Conclusion: This option is incorrect.

2. **Tomato**:
- Activation: Twisted (incorrect, it is valvate)
- Conclusion: This option is incorrect.

3. **Onion**:
- Bulbs: Modified stem (correct)
- Estivation: Imbricate (correct)
- Placentation: Axile (correct)
- Conclusion: This option is correct.

4. **Maize**:
- Dark reaction: P4 pathway (incorrect, it should be C4 pathway)
- Conclusion: This option is incorrect.

### Step 3: Identify the Correct Answer
From the analysis, only the characteristics of the onion are correctly matched. Therefore, the correct answer is **Onion**.

### Final Answer
The organism that is correctly matched with its three characteristics is **Onion**.
