Options

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

Answer

To solve the question of which plant does not belong to the same taxonomic family, we will analyze each option provided:

1. **Identify the plants and their scientific names:**
- **Solanum nigrum** (commonly known as black nightshade)
- **Petunia axillaris** (commonly known as white petunia)
- **Thora inoxia** (commonly known as thorny nightshade)
- **Pisum sativum** (commonly known as pea plant)

2. **Determine the taxonomic family of each plant:**
- **Solanum nigrum** belongs to the family **Solanaceae**.
- **Petunia axillaris** also belongs to the family **Solanaceae**.
- **Thora inoxia** belongs to the family **Solanaceae** as well.
- **Pisum sativum**, on the other hand, belongs to the family **Fabaceae** (also known as the legume family).

3. **Compare the families:**
- The first three plants (Solanum nigrum, Petunia axillaris, and Thora inoxia) are all part of the **Solanaceae** family.
- The fourth plant, Pisum sativum, is part of the **Fabaceae** family.

4. **Conclusion:**
- Since Pisum sativum does not belong to the same family as the other three plants, it is the correct answer to the question.

Therefore, the answer is **Pisum sativum (option D)**.
