Options

A. China rose family
B. Pea family
C. Potato family
D. Yucca family

Answer

To solve the question regarding which family exhibits both the monadelphous condition and a pentacarpellary ovary, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Monadelphous Condition**:
- Monadelphous refers to the condition where the filaments of the stamens are fused together to form a single bundle. This is a characteristic feature of certain flowering plants.

2. **Understanding Pentacarpellary Ovary**:
- Pentacarpellary means that there are five carpels (or pistils) that are either separate or fused together. This indicates that the ovary consists of five distinct sections or chambers.

3. **Identifying the Plant Families**:
- We need to analyze the options given in the question:
- **Option A: China rose family (Malvaceae)**
- **Option B: Pea family (Fabaceae)**
- **Option C: Potato family (Solanaceae)**
- **Option D: Yucca family (Agavaceae)**

4. **Researching Each Family**:
- **China Rose Family (Malvaceae)**: This family is known for having both monadelphous stamens and a pentacarpellary ovary.
- **Pea Family (Fabaceae)**: Typically does not exhibit monadelphous stamens.
- **Potato Family (Solanaceae)**: Generally does not show the monadelphous condition.
- **Yucca Family (Agavaceae)**: Also does not exhibit the monadelphous condition.

5. **Conclusion**:
- Based on the characteristics of the families, the China rose family (Malvaceae) is the only one that exhibits both the monadelphous condition and a pentacarpellary ovary. Therefore, the correct answer is **Option A: China rose family**.
