Character common between Liliaceae, Malvaceae ,Solanaceae is

Options

A. (a) Axile placentation
B. (b) Cohesion of stamens
C. (c) Both of these
D. (d) Monoadelphous

Answer

To determine the common character between the families Liliaceae, Malvaceae, and Solanaceae, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Families**: We are looking at three plant families: Liliaceae, Malvaceae, and Solanaceae.

2. **Examine the Options**: The options provided are:
- A) Exile placentation
- B) Cohesion of stamens
- C) Monoadelphous stamens
- D) Other characteristics

3. **Analyze Exile Placentation**:
- Exile placentation refers to the arrangement of ovules in the ovary where they are attached to the central axis.
- This type of placentation is indeed found in all three families: Liliaceae (e.g., onion), Malvaceae (e.g., cotton), and Solanaceae (e.g., potato).

4. **Check Cohesion of Stamens**:
- In Liliaceae, stamens are fused in two bundles (3 + 3).
- In Malvaceae, stamens are fused in a single bundle, but they can be more than five.
- In Solanaceae, stamens are free and exactly five in number.
- Since the cohesion of stamens differs among these families, this cannot be a common character.

5. **Evaluate Monoadelphous Condition**:
- Monoadelphous means that stamens are present in a single bundle.
- In Liliaceae, they are in two bundles; in Malvaceae, they are in a single bundle; and in Solanaceae, they are free.
- Therefore, this condition is not common across all three families.

6. **Conclude the Common Character**:
- After analyzing the options, we find that the only common character among Liliaceae, Malvaceae, and Solanaceae is **exile placentation**.
- Thus, the correct answer is option A: **Exile placentation**.

### Final Answer:
The character common between Liliaceae, Malvaceae, and Solanaceae is **exile placentation**.
