C) it built mill villages and gave jobs to whole families makes the most sense.
It is not A, because the textile industry should have created more factories to allow a greater production to help increase profits.
It is not B, because the textile industry would have added more jobs and allowed more money to flow into South Carolina, which should have greatly increase the economy of the state.
It is not D, because if new jobs were found inside South Carolina, it may lead to a increase population, as job-seekers move to South Carolina to find a paying job.
hope this helps
