Which of the following was an inspiration for medieval romances? Scandinavian epics Greek mythology Arthurian legends Aesop's fables

The correct answer should be Arthurian legends.

Medieval romances were written quite a bit about Arthur and his knights, as well as his beautiful wife, Guinevere. Romance in this sense of the word doesn't only mean tales about love, but also about knights, bravery, and fantastic adventures. Scandinavian epics, Greek mythology, and Aesop's fables weren't really a thing until Classicism, which came later.
