Which of the following best describes why malory's morte d'arthur is considered a medieval romance

A medieval romance involves kings and knights (and the chivalric code they must follow). A heroic knight is often the main character, and this hero often goes on a quest. Medieval romances frequently involve supernatural elements that add a mysterious tone to the story. These elements may include dragons or even magic. 
Other characteristics include a quest or an adventure, which often required a journey through a vast setting. Women are often idealized and the subject of courtly love. Disguises are often common, as in the case of Sir Gawain and the Green Knight.
Malory's Morte d'Arthur contains all of the above elements. This work contains supernatural elements, the presence of magic, a noble hero in the form of Arthur, his many chivalric knights, and a vast setting.
Therefore, the second statement is the correct answer. The statement, "It is a story about kings and knights and contains supernatural elements" best describes why Malory's Morte d'Arthur is a medieval romance.
