Which French ports were linked with slave trade?

Correct answer: Bordeaux and Nantes

The governing historical concept is France’s participation in the eighteenth-century Atlantic slave trade. French merchants and ships used important Atlantic ports, especially Bordeaux and Nantes, to organise or support commercial voyages connected with the triangular trade. Nantes became particularly prominent, while Bordeaux was also an important centre of maritime commerce. Therefore, option B is correct. Paris and Versailles were political and royal centres rather than the principal ports named in this context. Lyon was inland, and Rome and Nice do not identify the French Atlantic ports associated with this trade. The question asks for historically linked ports, not every city involved in colonial administration or commerce.
