Which of the following does not belong to the same taxonomic Family?

Options

A. Solanum nigrum
B. Petunia axillaris
C. Datura innoxia
D. Pisum sativum

Answer

To solve the question of which organism does not belong to the same taxonomic family, we will analyze the given options one by one.

### Step-by-Step Solution:

1. **Identify the First Organism: Solanum nigrum**
- **Taxonomic Family**: Solanaceae
- **Characteristics**: Bicarpillary, Axial placentation.

2. **Identify the Second Organism: Petunia**
- **Taxonomic Family**: Solanaceae
- **Characteristics**: Similar to Solanum nigrum, it also exhibits bicarpillary and axial placentation.

3. **Identify the Third Organism: Dhatura**
- **Taxonomic Family**: Solanaceae
- **Characteristics**: Like the previous two, it is bicarpillary and has axial placentation.

4. **Identify the Fourth Organism: Pisum sativum (Pea Plant)**
- **Taxonomic Family**: Fabaceae
- **Characteristics**: It has marginal placentation, which is different from the axial placentation seen in the previous three organisms.

5. **Conclusion**:
- The first three organisms (Solanum nigrum, Petunia, and Dhatura) belong to the Solanaceae family. However, Pisum sativum belongs to the Fabaceae family. Therefore, Pisum sativum does not belong to the same taxonomic family as the other three.

### Final Answer:
**Pisum sativum does not belong to the same taxonomic family as the others.**
