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 in 1876 was marked by the Compromise of 1877, which resulted in the withdrawal of federal troops from the South and the end of Reconstruction. This withdrawal allowed white southern Democrats to regain control of state governments, leading to the implementation of discriminatory laws and practices, including Jim Crow laws, which curtailed the rights and freedoms of African Americans.
