Which award recognizes a significant contribution to civil rights by an individual?

The Mary Church Terrell Award is designed to honor individuals who have made significant contributions to civil rights. Named after Mary Church Terrell, one of the first African American women to earn a college degree and a prominent activist for civil rights and women's suffrage, this award serves to recognize those who continue her legacy by advocating for justice, equality, and the rights of marginalized communities. The award emphasizes the importance of enduring activism and leadership in the ongoing struggle for civil rights, making it a fitting recognition for individuals whose efforts align with these ideals.

Each of the other options represents different forms of recognition but does not specifically highlight contributions to civil rights. The Osceola Award could focus on other areas of achievement, while the Patricia Roberts Harris Award acknowledges women in public service and the Delta Female Executive Award recognizes excellence in leadership among women. Therefore, the distinction of the Mary Church Terrell Award as being explicitly focused on civil rights sets it apart as the most appropriate choice in this context.
