Final answer:
The correct answer is option a) A gilded sword.
Step-by-step explanation:
In the epic poem Beowulf, the protagonist Beowulf gives the boat-warden a gilded sword.
This can be seen in the context of the poem when Beowulf sets off on a journey to fight the monstrous Grendel. As a symbol of honor and bravery, Beowulf presents the boat-warden with a valuable gilded sword before embarking on his quest.
The significance of this gift signifies the trust and respect Beowulf has for the boat-warden as a loyal ally and a guardian of his ship during his absence.
