Answer:
C.
Step-by-step explanation:
"Sayadio in Spirit-land" is an Iroquois legend. In this legend, a warrior named Sayadio goes to the spirit world to find the spirit of his sister and bring it back to the earth. When Sayadio arrived in the spirit world, everyone was dancing and feasting.
In the mythological story of "Valhalla: Hall of the Chosen Slain", the spirits of the great warrior were brought. Odin, the king of gods, would chose the mightiest of the might warriors' spirits to be brought in his kingdom. The spirit of the warriors rejoice being there.
Therefore, the similarity is that the spirits or the inhabitants of the otherworld in both the stories were content and happy.
Thus, option C is correct.
