Solanaceous members have-

Options

A. Parietal placentation
B. Basal placentation
C. Marginal placentation
D. Axile placentation.

Answer

**Step-by-Step Solution:**

1. **Understanding Solanaceous Members**: The term "Solanaceous" refers to plants that belong to the Solanaceae family, commonly known as the nightshade family. This family includes plants like potatoes, tomatoes, and eggplants.

2. **Defining Placentation**: Placentation is the arrangement of ovules within the ovary of a flower. It is important to identify the type of placentation to understand the reproductive structure of the plant.

3. **Identifying the Type of Placentation in Solanaceous Members**: In the Solanaceae family, the type of placentation observed is termed "exile placentation."

4. **Characteristics of Exile Placentation**:
- In exile placentation, the ovary is divided into compartments (locules).
- The Solanaceous members typically have three compartments in their ovaries.
- Each compartment contains two ovules, making the ovules bilocular.

5. **Conclusion**: Therefore, Solanaceous members exhibit exiled placentation, characterized by three compartments in the ovary with two ovules in each compartment.
