The primary factor that led to the French forces leaving the island of Saint-Domingue (now Haiti) was the successful rebellion led by Jean-Jacques Dessalines and other leaders against the French colonial authorities. Although Toussaint Louverture did play a crucial role in the early stages of the Haitian Revolution, he was captured in 1802 and died in prison in 1803. His capture did not end the struggle for independence, as Dessalines and others continued the fight against French colonial rule.
Ultimately, in 1804, the Haitian Revolution culminated in the declaration of independence, making Haiti the first independent nation in Latin America and the Caribbean.
While Napoleon Bonaparte had ambitions of restoring French control over the colony, the continued resistance from local forces, coupled with the impact of the Haitian Revolution and other complications (including military failures and the loss of support due to the Napoleonic Wars in Europe), led to the French retreat from the island.
So, while each of the statements has a connection to the events in Saint-Domingue, the most accurate encapsulation of the primary reason for the French forces leaving would be the successful rebellion led by Jean-Jacques Dessalines.
