Final answer:
In the game played by the host and Gawain at the castle, the host tells stories and Gawain gives gifts.
Step-by-step explanation:
The correct answer is C. Host: Stories; Gawain: Gifts.
In the game that the host and Gawain play while at the castle, each person exchanges different things on each day.
The host, who represents the Lord of the castle, shares stories with Gawain. The stories are a form of entertainment and serve as a way for the host to interact with Gawain.
Gawain, in return, gives gifts to the host. These gifts are a way for Gawain to show his appreciation and respect for the host's hospitality.
