Answer: A. mutual respect and loyalty.
In the epic poem Beowulf, we encounter King Hrothgar. The king's people are constantly attacked by a demon called Grendel, and the king has become too old to defend them. However, Beowulf is willing to help him. In exchange for riches and gratefulness, Beowulf destroys both Grendel and Grendel's mother. Both Beowulf and the king appreciate and respect each other. Moreover, Beowulf feels bound to the king by loyalty, which the king rewards fairly.
