In Terms of Southern Reconstruction, President Lincoln's Assassination Was Ironic

In terms of Southern Reconstruction, President Lincoln's assassination was ironic because:

A) Lincoln didn't want to facilitate meaningful Reconstruction policies anyway.
B) John Wilkes Booth perpetrated the assassination to "redeem"? the South, but Lincoln would have treated the former Confederacy much more favorably than his successors, had he lived.
C) Lincoln wanted to reunify the nation but would not have promoted racial integration, thus preserving the culture of white Southerners as it existed before the war.
D) Lincoln was terminally ill and would have died soon of natural causes anyway.
E) The former Confederacy was planning a second war against the Union, but the assassination united so many people that the advocates for renewed war feared they would be defeated quickly.
