Final answer:
The correct option is A. The Normans were descended from Vikings who settled in northwestern France in a region that would be known as Normandy. This settlement was established in 911 CE when lands were granted to Viking leader Rollo. The Normans had a notable impact on European history, particularly with the Norman Conquest of England.
Step-by-step explanation:
The Normans descended from Vikings who had seized and lived in northwestern France, particularly in the region known as Normandy, which became a significant duchy. This settlement was officially established in the year 911 CE when the Frankish King Charles the Simple granted the Viking leader Rollo lands in the northern part of his kingdom.
This was a strategic move to utilize the Vikings' strength to defend against further Viking incursions. Over time, the Normans in northern France would play a pivotal role in European history, especially with the Norman Conquest of England in 1066, led by William the Conqueror, who was a direct descendant of those Viking settlers.
