Answer:
B) The number of years the person worked for his or her master.
Step-by-step explanation:
Indentured servitude was a system of unfree labor by which an employee is bound by a signed or forced contract to work for a particular employer for a fixed time.
Indentured servants usually entered into that labor for a specific payment or other benefits. When the contract finished the servants were given their freedom, and occasionally plots of land.
