Which one is correctly matched with its three characteristics

Options

A. Pea-C_(3), endospermic seed,vaxillary aestivation
B. Tomato-twished aestivation, axile placentation, berry
C. Onion-Bulb, imbricate aestivation,axile placentation
D. Maiza-C_(3) pathway, closed vascular bundles, scutellum.

Answer

To determine which option is correctly matched with its three characteristics, let's analyze each option step by step:

### Step 1: Analyze the first option - Pea
- **Characteristics**: P cycle, endospermic seed, vacillary estivation.
- **Analysis**:
- Peas are known to exhibit the C3 and C4 photosynthetic pathways, but they primarily show the C3 cycle.
- Therefore, the statement about the P cycle is incorrect.
- Conclusion: **Not correctly matched.**

### Step 2: Analyze the second option - Tomato
- **Characteristics**: Twisted estivation, axial placentation, berry.
- **Analysis**:
- In tomatoes, the arrangement of petals and sepals is imbricate, not twisted.
- However, tomatoes do produce berries and exhibit axial placentation.
- Conclusion: **Not correctly matched due to the incorrect estivation type.**

### Step 3: Analyze the third option - Onion
- **Characteristics**: Bulb type underground stem, imbricate estivation, axial placentation.
- **Analysis**:
- Onions are indeed a bulb type of underground modified stem.
- They exhibit imbricate estivation and axial placentation.
- Conclusion: **Correctly matched.**

### Step 4: Analyze the fourth option - Maize
- **Characteristics**: Monocotyledonous grain, C4 pathway, scutellum present.
- **Analysis**:
- Maize is a monocot and does show the C4 pathway.
- The scutellum is a part of the seed structure, but the statement about the C3 pathway is incorrect.
- Conclusion: **Not correctly matched.**

### Final Conclusion:
The only option that is correctly matched with all three characteristics is **Onion**.
