Why would it be wrong to study sugar coffee indigo and tobacco separately from slave labour?

Correct answer: Because these were profitable cash crops produced by slave labour on plantations

Sugar, coffee, indigo and tobacco were important commercial crops in the Atlantic colonial economy. They were grown on plantations and were produced in large quantities for distant markets, especially European consumers. Such production needed intensive labour for planting, tending, harvesting and processing. Enslaved people supplied much of this labour under coercive conditions. Studying these crops without slavery would therefore hide the social system that made their large-scale and profitable production possible. The crop, labour and market must be understood together.

Option A is correct because it identifies these goods as profitable plantation crops connected with enslaved labour. The other options are unrelated: the crops were not names of Bastille walls, political parties of the National Assembly or titles of French kings. The question tests whether students can connect ordinary commodities with the labour system behind them. European demand encouraged plantation expansion, while forced labour helped owners keep production profitable.
