Secret diplomacy was a major factor based on the fact that led to fear between all the nations and confusion. Nationalism and imperialism is a factor, scramble for Africa, Archduke fradana has some ties based that his death lead to more retaliation in the Balkans which wanted to be independents do Austria-Hungary and Russia fought over for.
The choices are D) Symmetry and Balance. And B)
The answer really depends on which of the 13 Southern states you are referring to. Each state issued their own Ordinance of Secession, in either 1860 or 1861. Hope this helps.
