Which characteristic is commonly found in fairy tales?

Fairy tales are often defined by their magical elements and the presence of a happy ending, which is a staple feature of the genre. The incorporation of fantastical elements such as talking animals, enchanted objects, and whimsical adventures sets fairy tales apart from other types of stories. These elements create a sense of wonder and imagination that appeals to readers and listeners of all ages.

Additionally, the typical structure of fairy tales leads to resolutions where good ultimately triumphs over evil, resulting in a happy ending. This pattern of storytelling is comforting and reinforces moral lessons, making it a hallmark trait of the genre. The other characteristics mentioned, such as complex characters with ambiguous morals, realistic settings with detailed timelines, or a focus on historical events, do not align with the traditional framework of fairy tales, which is centered around fantastical narratives and optimistic conclusions.
