(HELP ME) Kyle writes an essay about indentured servants in the 1800s:

Essay:
Unlike the colonial era, indentured servants in the 1800s were mostly born in the United States. Many indentured servants were young people who hoped to gain a better life after a period of work. They committed themselves to a master for a period of several years. The master usually paid some of their expenses and was required to free them at the end of their contract period.

Which statement corrects a mistake in Kyle's essay?

(A.) Indentured servants in the early 1800s were usually immigrants.
(B.) Most indentured servants were older people who had fallen on hard times.
(C.) Indentured servants had the right to stop working whenever they wished.
(D.)Masters rarely freed indentured servants at the end of a contract.
