What was the significance of the state of Kentucky at the start of the war?

A) As one of the first states to secede, it became a model for most of the other Confederate states in terms of the composition of its legislature and governorship.
B) Because it was a neutral, slaveholding state, Lincoln was determined to bring it to the Union side to make victory more likely and suppressed all talk of abolition.
C) Although a border state, because the Union had long had a stronger economy, it immediately threw its support to the North and helped guarantee the North would win.
D) Due to its initially neutral status during the war, most Native Americans and immigrants moved there and managed to avoid joining the fray.
E) As the only Confederate state to have outlawed the system of slavery before the start of the war, it represented the future to come for the rest of the Confederate states.
