D) President Lincoln was assassinated.

Explanation:

The assassination of Abraham Lincoln took place on April 14, 1865 around 22:25 in Washington, DC, when the American Civil War was coming to an end. Although he initially survived the shooting, the injuries received were of such severity that he died the next day, at 7:22. The incident occurred five days after the commanding general of the Army of Northern Virginia, Robert E. Lee, surrendered his troops to General Ulysses S. Grant and the Army of the Potomac. Lincoln was the first president of the United States to be assassinated, because thirty years earlier, in 1835, had failed an assassination attempt on Andrew Jackson.
