The correct answer is - Norse.
The English language adopted Norse words after the Viking invasion of this island country. The Nose language is in the family of Germanic languages, more specifically, from the North Germanic branch, and it was a language that was used in Scandinavia. This means that with the adopting of Norse words, the English language got Germanic influence into it. The closest modern day language to the original Norse language is the Icelandic, and not far behind is the Norwegian language.
