Answer: Option D.
Explanation: The middle colonies include New York, Pennsylvania, New Jersey, and Delaware.
The middle colonies were located between the Southern and British North American colonies, making them prone to trade and constant migration. Trading ports were established in particular states which attracted a diverse ethnic group of traders and entrepreneurs. The middle colonies also had geographic features vital to agriculture such as fertile soil, access to streams, and forests that were cultivated.
Additionally, the middle colonies were a safe haven of religious tolerance, which was not widely supported by southern and New England colonies. The initial settlement of Quakers in Pennsylvania attracted other religious groups as the population increased significantly.
Because the middle colonies was comprised of culturally diverse migrants, it brought a mix of settlers because people came from many cultures.
