The correct response is:
D. Hayes ended Reconstruction, which negatively impacted the African American community by returning power to white southern politicians.
The election of Rutherford B. Hayes and the subsequent Compromise of 1877 effectively marked the end of Reconstruction, leading to the withdrawal of federal troops from the South. This allowed white southern politicians to regain control and implement policies that disenfranchised African Americans, leading to increased segregation and the establishment of Jim Crow laws.
