Answer: B. He ended the mass execution of white Haitians by former slaves and affranchis.
Step-by-step explanation:
Toussaint Louverture led thousands of slaves to freedom through the slave revolt in the French colony of Saint-Domingue (Haiti).

Among all the rulers who attempted to make the island into a federal state, he was the only one to succeed.
