The correct Answer is:
### Step-by-Step Solution: 1. **Understanding the Question**: The question asks about the reproductive anatomy of female birds, specifically regarding their ovaries. 2. **Identifying the Relevant Biological Group**: Female birds belong to the class Aves, which is part of the phylum Chordata. This is important as it helps us understand their biological characteristics. 3. **Understanding Ovarian Structure**: In female birds, the ovaries are the reproductive organs responsible for producing eggs. 4. **Functional Ovary in Birds**: In most avian species, only the left ovary is functional. The left ovary is responsible for the production of eggs. 5. **Vestigial Right Ovary**: The right ovary is present but is vestigial, meaning it has lost its function over time. This occurs during embryonic development when the right ovary regresses and does not develop fully. 6. **Conclusion**: Therefore, the correct statement about female birds is that they have paired ovaries, with the left ovary being functional and the right ovary being vestigial. 7. **Final Answer**: The correct answer is that female birds have paired ovaries, with the left one functional and the right one vestigial.
