In Addition to Resulting in the President's Death, How Did

In addition to resulting in the president's death, how did Lincoln's assassination prove significant?

A) It had been in response to Lincoln's passionate calls for a vengeful peace, and to honor his wishes, his supporters resolved to do everything in their power to violently retaliate against the South.
B) It caused northerners to overwhelmingly reject the message of the Radical Republicans and to throw their support behind the conservative Republicans in large numbers.
C) It ensured that economic policies designed to spur industrial development across the country would immediately go into effect in the weeks following Lincoln's death.
D) It went largely unrecognized by much of the country because Americans were still distracted by the carnage of war, so Johnson went on to pursue only policies identical to Lincoln's.
E) It resulted in an immense outpouring of grief across the country but decreased the possibility of a lenient federal Reconstruction of the Confederacy like Lincoln had envisioned.
