Option c is the correct answer. The African slaves were brutally brought to America for replacement of the native working population who died off.
African immigrants or the slaves to North America also brought their native trades and skills, and the continent's economy and agriculture benefited from their knowledge. The Northwest frontier's rivers and canals were made navigable for boats by West Africans with experience in their own country's waterways, and experienced African cattle drivers were able to use their expertise with ox teams and livestock.
Large-scale rice and indigo cultivation were practices that many Africans were intimately familiar with but that European Americans knew nothing about; without the knowledge of Africans and their ancestors, the rice fields of South Carolina and Louisiana might not have been cultivated.
African slaves were imported into America to take the place of the native working populations that perished. Therefore option c is correct.
