Lincoln's 1857 Emancipation Proclamation warned that the issue of slavery could destroy the nation.

Option A

Explanation:

This proclamation was given by Abraham Lincoln when the civil war was in its third year. The proclamation changed the status of almost 3.5 million slaves. The slaves were freed post the proclamation.

Slavery was a major issue that had led to the civil war and this proclamation changed the manner in which slavery was viewed.

The proclamation made freeing the slaves an explicit goal of the war. The proclamation did not lead to immediate abolition of slavery but ensured that most of the slaves in the Union were freed.
