What is a characteristic feature of a ballad?

A ballad is typically recognized as a narrative poem that is often set to music and sung. This form of poetry is known for telling a story, usually recounting dramatic or romantic events, often in a straightforward and repetitive style that enhances its musical quality. Ballads commonly feature lyrical expressions of emotion, the portrayal of characters and their experiences, or historical narratives that appeal to a wide audience.

The other options do not align with the defining characteristics of a ballad. Prose form is distinct from poetic forms, and ballads are recognized for their poetic and rhythmic structure. While some ballads might involve characters with unique traits or powers, this is not a defining feature, as many ballads focus on ordinary characters and universal human experiences. Lastly, ballads can explore a range of themes, including humor, and are not confined to serious subjects. This versatility in content is part of what makes them engaging and relatable to different audiences.
