The correct answer is C) coastal zone.
The area of South Carolina where the population was GREATEST during colonial times was the coastal zone.
South Carolina was one of the most productive colonies in North America due to the number of crops they produced. It was founded in 1663 and its fertile soil was a key factor for growing crops as well as favorable weather conditions. South Carolina plantations heavily benefited from slaves to grow crops such as indigo, rice, tobacco, and cotton. Most of the people in that time used to live in the coastal zone.
