B. Because the race for President was so close between Rutherford Hayes and Samuel Tilden

Explanation:

The Hayes-Tilden election was one of the closest in American history. Tilden, who was a Democrat, had won the majority vote but not the electoral college and was short of only 1 vote there. There were still 3 states which had not declared a winner officially and they had 20 votes which would make Hayes the winner if he got them.

The Hayes-Tilden Electoral Commission was then established to review the results of the election to see how it can be resolved. The dispute ended when the Democrats decided to award Hayes all the votes provided that the Republicans allowed for the withdrawal of Federal troops from the South.
