Final answer:
Serfs were bound to the land and under the authority of a lord, making them dependent on the lord for protection and dispute resolution. The statement that serfs were self-sufficient is false.
Step-by-step explanation:
The statement that serfs were dependent on only themselves is False. Serfs were not self-sufficient but were instead bound to the land and under the authority of a lord. Under the feudal system, serfs provided labor and were obligated to give a portion of their produce to their lord, who in return had certain responsibilities such as protection and dispute resolution. Serfdom was a condition of bondage that lasted until the mid-19th century in some places, such as Russia, and the abolition of serfdom did not necessarily mean that the lives of the serfs improved immediately.
