During this period, Spain was dealing with plenty of troubles in South America, so it was not very interested in Florida. This is why in 1819 it accepted to cede Florida to the United States and estables a new limit frontier. Also, around this time, the U.S. admitted Louisiana, Indiana, Mississippi, Illinois, Alabama, Maine and Missouri into the Union.

Thus the right answer is option A. The U.S. purchased the Florida Territory from Spain and seven states were admitted into the union.
