Why is it necessary to study European market demand and slave labour together?

Correct answer: Because European consumption kept colonial slave labour profitable

The governing concept is the economic connection between consumer demand and colonial exploitation. European consumers wanted products such as sugar, coffee, tobacco and cotton in increasing quantities. Plantation owners responded by expanding production, and this expansion depended heavily on the forced labour of enslaved Africans. The profits earned from plantation exports encouraged merchants, shippers and owners to continue the slave-trading system. Thus option A is correct: demand did not merely exist separately from slavery; it helped make slave labour commercially profitable. Options B, C and D contradict the historical relationship because demand did not make enslaved people ministers, did not stop the trade, and Europe was deeply connected with colonial economies.
