B) It leaves the impression of an unambiguously happy ending.
Explanation:
This Japanese Folktale has an apparent clearly happy ending because the main character, Momotaro, defeated the chief of the devils. This excerpt starts with "After this..." and this refers to a fight Momotaro had with Akandoji. Momotaro beat him in a fair fight and tied him with a rope. The chief of devils ,then, surrendered and gave to Momotaro all his riches. This event made Momotaro become a hero ; he would be honoured and congratulated.
