The correct answer is - b. England disagreed with the southern leaders.
The political views of the leaders of the South were much different to those of the leaders of the North. The prime reason for dispute being the slavery, with the North being against slavery, and the South being pro-slavery.
England was much closer in its political views with the North, especially with the issue of the slavery, as England was also propagating for the abolishing of the slavery. Because of this, when it came time for choosing sides, England choose the side with which it had more common things, or rather with the side that was on the same political frequency with it.
