civil war?

b. it completed the strategy outlined in the anaconda plan.
c. it ensured the reelection of abraham lincoln to a second term in office.
d. it outlawed the idea of secession and provided a way for southern states to rejoin the union

The right answer is:

A.It shifted the purpose of the war from preserving the Union to freeing the slaves.

Explanation:

Freeing slaves became a legitimate war objective after the Emancipation Proclamation of January 1, 1863. It was made possible only because of Lincoln´s firm commitment to issuing the document and after the Battle of Antietam that allowed the Union to expel the Confederates from Maryland, an event seen as a "victory."
