Which of the following caused plantation owners to start using more slaves and few indentured servants?

B. The price of indentured servants increased because the trip to America became more expensive.

Explanation:

"Indentured servitude" is different from "slavery." Indentured servitude refers to providing service or work without pay through a contract. The indentured servant signs a contract that he will be giving his service to his master as a form of payment for his transportation to immigrate to a place, a debt bondage and other similar obligations. Although they were not paid, they were given a place to stay and food to eat.

This was the case before, however, conditions changed when America and Britain passed laws in order to help the indenture service decline. An example of this is the "Passenger's Vessels Act 1803" by the UK Parliament. This made the transportation more expensive (specifically, in North America) thus, it became a problem for landlord's who were seeking to attain indentured service.

So, this explains the answer.
