In the early and mid 1800s the majority of the southern economy depended on a) unskilled labor supplied by immigrants b) goods manufactured by skilled craftsmen c) advances in manufacturing technology d) labor provided by enslaved workers

Option: D) Labor provided by enslaved workers.

Explanation:

In the early and mid-1800s, the majority of the Southern economy depended on the enslaved workers (slaves). The southern States were able to prosper in as agricultural states because of the geographical condition which allows them to grow cash crops like cotton, tobacco, corn, rice and sugar. The South required labors to work in the fields to provide productivity. The southern states were introduced to the enslaved African, as they were hard-working people and were cheap compared to the indentured servants.
