Answer:
A. They were regarded as the property of the noble whose fields
they worked.
Explanation:
Serfdom represented a set of legal norms enshrining a prohibition for peasants leaving their land allotments without the permission of the authorities (that is, peasants attached to the land; runaways were subject to forced return), hereditary subordination of administrative and judicial authorities of a certain feudal lord, depriving peasants of the right to alienate land plots and acquire real estate, sometimes - an opportunity for the feudal lord to alienate peasants without land. In its most severe manifestations, serfdom is approaching slavery.
Serfs worked land owned by the king
Knights served large landholders by defending their lands
A serf would work the land, a knight would protect it, a vassal would govern it, and the lord would reap the benefits.
Feudalism means the nobility would hold lands for people in exchange for service or military service.
