Hi there! The answer is A. The Civil War.

The Civil War (lasting from 1861 to 1865) was mainly caused by the economic, cultural and political consequences of slavery. In those years there the northern and southern states of the US differed a lot in their opinion about slavery, which eventually caused a war.
