The correct answer is B) abolished slavery by military order.
When the Civil War ended, the Union took control of Florida's government and abolished slavery by military order.
Union General Edward M. McCook received the order in May 1865, to establish federal authority and control in the Florida territory. That is when General Scott surrender its Confederated troops to the Union General. Days later, McCook read the Emancipation Letter of President Abraham Lincoln in the Tallahassee state capitol, where people raised the United States flag.
