The correct answer is D. Where the first shots of the civil war were fired.
Explanation
Fort Sumter was a fort built in the Atlantic Ocean in the state of South Carolina in 1829 by the end of the Anglo-American conflict of 1819. From there it was possible to control the maritime traffic entering and leaving the state.
During the war of secession, after the declaration of separation by South Carolina, the army of the union sent troops to the Fort Sumter from where they made resistance to the separation until the attacks started by the Confederates on the 12th of April of 1961 causing the withdrawal of the troops hosted there and officially beginning war, being the first battle event of the civil war of the United States. So the correct answer is D. Where the first shots of the civil war were fired.
