Answer:
B.
Explanation:
Abraham Lincoln wanted to know that the states would be loyal afterwards and would not secede from the union again. The Civil War was not even about the issue of slavery, it was about keeping the union together. This is true because if Lincoln made it about the slave issue, he would have lost the support of the neutral slave states. This rules out option A. C is not true because it had nothing to do with keeping the state in the union, and D is not correct because much more money was lost rather than gained from the civil war.
