How did European consumption habits sustain slavery?

Correct answer: Demand for sugar and coffee kept slave-labour plantations profitable

The governing concept is the relationship between consumer demand, colonial production and forced labour. Sugar and coffee became important consumer goods in Europe, so plantation owners and merchants had strong incentives to expand production. In many colonies, this production depended on enslaved labour, and the sale of plantation goods generated profits that helped maintain the system. Option A is correct because it explains how everyday consumption could support an exploitative colonial economy. Option B is the opposite of the historical relationship. Option C ignores the close connection between European markets and colonies. Option D is geographically and historically absurd: the Bastille was a prison in Paris, not a plantation or production centre.
