Final answer:
The Freedmen's Bureau's educational efforts resulted in the establishment of over 4,000 schools, the education of nearly a quarter of a million students, and the seeding of historical educational institutions like Fisk University. Option a is the correct answer.
Step-by-step explanation:
The educational efforts by the Freedmen's Bureau had prolific and lasting impacts. In the early stages of its operation, the Bureau established over 4,000 schools and taught approximately 247,000 students. Despite external and internal challenges, the fruits of its labors were evident, as the schools provided education not only for freedpeople but also for poor White people.
The establishment of these institutions allowed many freed individuals to learn to read and pursue higher education. These efforts laid the groundwork for future educational advancements and was instrumental in the creation of respected institutions like Fisk University, Hampton University, and Dillard University. Despite the closure of the Freedmen's Bureau, its influence in education was profound and ongoing.
Therefore, the correct option summarizing the outcome of the agency's educational efforts is A. It established dozens of schools that remained opened long term.
