The correct answer is B. cede Florida to the United States
In 1818 American troops captured the entire western part of the Floridas, that during that time was a Spanish territory. Americans also pressured Spain by supporting the independence movements forming in Latin America. Because of this situation, the Adams-OnĂs Treaty was signed. In this treaty, Spain ceded Florida to the US, but they also agreed to settle a boundary between Louisiana and Spanish territory in the West.
