Around 1066, The Normans conquered England under William the Conqueror.
The Norman conquest linked England tighter to Continental Europe, especially west Europe, and William the Conqueror, king of England, was technically the king of France's vassal, so his lands lodged in a region of France bigger than the royal realm. Besides, he got help from King Henry I of France to remain as ruler.
Thereby the answer is (C) & (D), due The Normans that invaded England came from Normandy in Northern France, although they were originally from Scandinavia, and a previous French King conceded some land to the Vikings in Northern France earlier.
