Answer:
B. The king of England claimed a right to become the king of France.
Explanation:
The rivalry between France and England came from the Battle of Hastings (1066) when the victory of Duke William of Normandy allowed him to take over England. Now the Normans were kings of a great nation and would demand the French king be treated as such. But the point of view of France was not the same: the Duchy of Normandy had always been a vassal, and the fact that the Normans had ascended to England's throne did not have to change the traditional submission of the dukedom to the crown of Paris. Therefore, in the following centuries, English monarchs accumulated enormous possessions in French territories, that took the English crown and the French crown to a great conflict. At the beginning of the 14th century, there was a dynastic turmoil in the French crown, that took the new English king, Edward III, to claim the right to rule the Kingdom of France. The war started in the year 1337 and lasted until 1453.
