The above- listed conditions are characteristics of the which family of plants?

Options

A. Solanaceae
B. Fabaceae
C. Lilaceae
D. Brassicaceae

Answer

To solve the question regarding the characteristics of a plant and identify its family, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Characteristics**:
- The plant has a **racemose inflorescence**.
- It has **zygomorphic flowers**.
- The flowers consist of **five sepals and five petals**.
- The petals show **vexillary aestivation**.
- It has a **monocarpellary and unilocular superior ovary**.
- The androecium consists of **ten stamens**.

2. **Analyze Each Option**:
- **Option 1: Solanaceae**:
- This family typically has cymose inflorescence, which does not match the given racemose inflorescence. Therefore, this option is incorrect.
- **Option 2: Fabaceae**:
- This family is known for having racemose inflorescence, zygomorphic flowers, five sepals and petals, vexillary aestivation, a monocarpellary ovary, and ten stamens. This matches all the characteristics given in the question. Thus, this is a strong candidate.
- **Option 3: Liliaceae**:
- Members of this family usually have actinomorphic flowers, which do not match the zygomorphic requirement. Hence, this option is incorrect.
- **Option 4: Brassicaceae**:
- This family also typically has actinomorphic flowers and does not meet the zygomorphic criterion. Therefore, this option is also incorrect.

3. **Conclusion**:
- Based on the analysis, the only family that fits all the provided characteristics is **Fabaceae**.

### Final Answer:
The plant belongs to the **Fabaceae** family.
