What was the main economic use of slave labour in French colonies?

Correct answer: Producing sugar, coffee and tobacco on plantations

The governing concept is plantation slavery as a labour system designed for export agriculture. In French Caribbean colonies, enslaved people were forced to clear land, plant crops, maintain fields, harvest produce and process it for overseas trade. Sugar was especially important, while coffee and tobacco were also major plantation commodities. These products were shipped to European markets and produced wealth for plantation owners, merchants and colonial trading networks. Therefore option B correctly identifies the main economic use of enslaved labour. Giving speeches at court, voting in the Estates General and writing Church laws were not the productive functions for which plantation owners enslaved people. The distractors refer to political, royal or religious activities rather than the agricultural labour that sustained the colonial economy.
