The correct answer is 4) were needed as workers on plantations

Explanation:

Indentured servitude was a system of cheap or free labor that became very popular in the colonies. In this system, an individual signed an indenture or contract of working for some years in exchange for some benefit that was usually transportation to the New World along with food and shelter when he or she arrived.

This means individuals who accept this contract had to pay back with work for the benefits received. Additionally, once the period of service ended it was common servants continue worked plantations where they received some payment or benefit for their work, this occurred because indentured servants already had experience in growing crops or other activities related to land and also they work for less money than regular workers.
