The correct answer is B. The Louisiana territory was no longer useful to him after a slave revolt resulted in the independence of Haiti.
Napoleon Bonaparte's decision to sell the Louisiana Territory to the United States in 1803 was significantly influenced by the Haitian Revolution, which led to the establishment of Haiti as an independent nation. The loss of Haiti diminished France's ability to maintain a colonial empire in North America, as Haiti was seen as a crucial base for French operations in the region. Consequently, Napoleon decided to sell the territory to raise funds for his military campaigns in Europe and to focus on matters closer to home.
