The correct statement regarding the impact of the election of 1876 on Reconstruction is:
The controversy over the election drove a compromise that ended Reconstruction.
The election of 1876 between Rutherford B. Hayes and Samuel J. Tilden was one of the most contentious in U.S. history, marked by allegations of voter fraud and disputes over electoral votes. The Compromise of 1877 was reached to resolve the electoral deadlock, which effectively resulted in the withdrawal of federal troops from the South and the end of Reconstruction. This compromise allowed Hayes to assume the presidency while the Democrats regained control of the southern states, leading to the dismantling of many advances made during Reconstruction for African Americans.
