The choices for this question can be found elsewhere and as follows:
A.)about supernatural beings.
B.)a tale of King Arthur’s knights.
C.) about an idealized hero.
D.) a tragic story of betrayed lovers.
I think the correct answer is option B. A medieval romance narrative in prose or poetry always tells a tale of King Arthur’s knights.
