Answer:
The correct answer is Feudalism began to spread to Britain soon after C. William the Conqueror invaded Britain.
Step-by-step explanation:
Feudalism was a system structured around several levels of land ownership. This system was implemented in Britain after William I - also known as William the Conqueror - defeated Harold at the Battle of Hastings in 1066. Once he became king of England, William I confiscated land from the Saxon lords and gave it to his own family and other Norman lords who became his vassals.
