The statement that BEST describes the economy of the Mid-Atlantic/Middle colonies is "They grew much of the grains that fed the thirteen colonies."

The Middle colonies were Pennsylvania, New York, Delaware, and New Jersey. They were formed by a diversity of ethnicities such as Sweden, Dutch, English, and Germans. The territories of the Middle colonies were fertile and the climate conditions allowed farmers to grow many grains. Indeed, they were known as "the Breadbasket of America" for the many and good quality crops the produced, traded, and exported.
