The correct answer is D.
The Vikings fought the local people, stealing from churches and burning buildings to the ground.
The name Viking means 'a pirate raid'. Vikings were people from Scandinavia who left their homeland and traveled by longboat to other countries, mostly Britain and Ireland. They invaded Britain in AD 793 and lasted till 1066.
The first place the Vikings raided in Britain was the monastery at Lindisfarne.
Since the Vikings were pagans and not Christians, so they raided many monasteries. Monasteries were an easy target for them as the monks had no weapons and the monasteries were filled with valuable treasures: gold, jewels and books.
