Answer:
The correct answer is A. President Lincoln was assassinated after Robert E. Lee surrendered.
Step-by-step explanation:
The assassination of Abraham Lincoln took place on April 14, 1865 around 22:25 in Washington, DC, when the 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 killed.
