The correct answer is B. The expansion of the Atlantic slave trade.
Explanation
During the colonial period between the 18th and 19th centuries, the American colonies of the European nations grew exponentially, there was more control over the land and the production of hundreds of crops and exploitation of minerals such as gold and silver had filled Europe with these means. Towards the middle of the 19th century, cotton production from India could not produce large quantities of cotton that European factories needed, added to the high costs that this meant. This allowed European factories to take advantage of the high cotton production that was being generated in the American colonies by African slaves who had been traded in the Atlantic and the Caribbean for work. According to the above, the correct answer is B. The expansion of the Atlantic slave trade.
