Answer:
The correct answer is A. President Lincoln used blockades to cut trade from the Confederate states with the rest of the world.
Explanation:
President Lincoln, fearful that the former European enemies of the United States (especially France and Great Britain) supported the Confederacy, carried out various strategies to avoid Confederate trade with these countries, in addition to other minor measures such as intimidation not to trade under the threat of considering European countries that bought goods from the Confederation as enemies. But the biggest strategy was the blockade of the interior waters and the seaports of the Confederacy: the Mississippi River was the scene of great battles, and the ports of New Orleans and Florida were continually attacked, to prevent the exit of cotton and other natural resources towards Europe. In this way, Lincoln isolated and defied the Confederacy, which in the future was a determining factor in the outcome of the Civil War.
