Answer:
Correct answer is Spain abandoned its territorial claims on lands north of Florida and east of the Mississippi.
Explanation:
First option is wrong because there is no territory south of Florida that was an issue between two countries.
Second one also is wrong because Spain couldn't claim territories to the North of Florida, or west of New Orleans, as they were not part of the dispute and were American territories.
