Tetramerous flowers with superior ovary is characteristic of

Options

A. Brassicaeceae
B. Papilionaceae
C. Cucurbitaceae
D. Solanaceae

Answer

To determine which family of plants is characterized by tetramerous flowers with a superior ovary, we can follow these steps:

### Step-by-Step Solution:

1. **Understand Tetramerous Flowers**:
- Tetramerous flowers are defined as having four petals. This is an important characteristic to identify the correct plant family.

2. **Identify Superior Ovary**:
- A superior ovary means that the ovary is positioned above the attachment of the petals and sepals. This arrangement is crucial for distinguishing between different plant families.

3. **Examine Plant Families**:
- We need to look at various plant families and see which ones have tetramerous flowers and a superior ovary.

4. **Analyze the Options**:
- **Brassicaceae (Mustard Family)**: This family is known for having flowers with four petals and a superior ovary. Therefore, it fits the criteria.
- **Papilionoideae (Legume Family)**: Typically has five petals, so it does not fit the tetramerous criterion.
- **Cucurbitaceae (Gourd Family)**: Also has five petals, thus does not meet the requirement.
- **Solanaceae (Nightshade Family)**: This family generally has five petals as well, which disqualifies it.

5. **Conclusion**:
- The only family that meets both criteria of having tetramerous flowers and a superior ovary is **Brassicaceae**, also known as the mustard family.

### Final Answer:
Tetramerous flowers with a superior ovary are characteristic of the **Brassicaceae** family (Mustard family).
