Answer:
B)To outline the practical effects of abolishing slavery.
Step-by-step explanation:
This was the main purpose of the Emancipation Proclamation. In this text, Lincoln outlines the practical effects of abolishing slavery. He tells us where the proclamation will take place, which slaves are going to benefit from it, and what this means for the future. The proclamation deals mostly with practical matters, and does not present a deep or complex discussion of the morality of emancipation or of slavery.
