The compromise of 1877 resulted in all of these except a) the end of reconstruction. b) the beginning of jim crow in the south. c) the removal of federal troops from the south. d) the control of congress by the radical republicans

The correct answer is B.

The Compromise of 1877 has an informal agreement reached during the due to the intense competition in the presidential elections in 1976. The agreement decided to remove federal troops from the Southern States and this was the formal ending of the Reconstruction era. Moreover, the Republican Hayes was appointed President instead of the Democrat Tilden. All these provisions were part of the deal.

On the other hand, Jim Crow Laws were contemporary to the other options listed, and also a consequence of the situation during and at the end of the Reconstruction era, but they were not directly implemented by the Compromise of 1877. The Jim Crow laws were used to enforce segregation in terms of race in the Southern states, circumventing the non-discrimination provisions of the 14th and 15th amendments of the US Constitution.
