The correct answer is B) Maryland. Maryland was a border state, because it had not declared secession from the Union. Although they did not declare secession from the Union, many men fought alongside the Confederate Army and the general consensus of the states who were border states was dismay in Abraham Lincoln called for troops to capture Southern positions. Some of the border states were fifty/fifity in regards to pro-union and pro-confederate stances, although this was not the case in Maryland.
