Which organization sponsored FBLA before it gained its independent status?

The correct answer is A, the National Business Education Association. Before FBLA (Future Business Leaders of America) achieved its independent status, it was sponsored by this association, which focused on promoting business education in the United States. The National Business Education Association played a significant role in providing support and resources for the development and growth of FBLA. This sponsorship helped establish the organization within schools and communities, allowing it to build a strong foundation for leadership and professional development among students interested in business careers.

The other options, while related to business and education, either did not have the same historical sponsorship role with FBLA or do not align with the timeline of FBLA's development. The American Management Association and the Business Professionals of America are distinct organizations that represent different aspects of business education and youth leadership, but neither served as the primary sponsor for FBLA during its early years. The National Education Association, while focused on education as a whole, does not have a direct connection to the founding of FBLA.
