When their period of service ended, indentured servants
a) were forced to pay a fee to gain freedom.
b) were forced into slavery.
c) had land they owned taken away.
d) were needed as workers on plantations.

I believe the answer is: d. were needed as workers on plantations.

indentured servants exist during the colonial period in Virginia. It filled with a group of people who decided to sign a work contract in exchange for transportation to Virginia along with food clothing and shelters.
when their contract is ended, most of them were still left with nothing and they have no choice but to signed another contract as plantation workers.

The right answer for the question that is being asked and shown above is that: "D) were needed as workers on plantations." When their period of service ended, indentured servants D) were needed as workers on plantations.
