Answer:
Louisiana is the correct answer.
Step-by-step explanation:
Napoleon Bonaparte had decided to sell the Louisiana territory to US as he was money strapped due to war with Great Britain. Haitian revolution and British naval blockade also compelled the french to offer this territory to the US. President Thomas Jefferson sent James Monroe to help Livingstone in 1803 to negotiate for new Orleans and some part of Florida as he wanted US to stretch across entire continent. Livingstone and Monroe signed Louisiana purchase treaty on April 30, 1803 and paid 15 million dollars.
