Answer:
Character vs. Character.
Step-by-step explanation:
In a literary work of art, the conflict is when there are two or more opposing forces that will eventually lead to the rising action and thus lead to another major conflict between the characters or themes/ ideas. This conflict in any plot gives a sense of suspense and holds the readers' interest, making them more absorbed into the story.
In the given excerpt, the conflict is that of a character against another character. This is seen when the giant taunts King Arthur to fight him, revealing his conditions too. If he wins, King Arthur will be put in captive along with "other brave knights" in a dungeon and if he yields, he will still be held in ransom. The giant also feels confident of his victory over the King, laying out his conditions even before the King can reply. This conflict is that of the giant's character against that of the king's.
