Which statement describes a flashback?

A flashback is a narrative device that allows the writer to return to an earlier time in the story to provide important background information or context for the events unfolding in the main timeline. This technique helps deepen the reader's understanding of characters, plot, and setting by revealing past experiences that influence present actions and decisions.

When a scene occurs that is set earlier than the main story, it gives insight into motivations, relationships, or significant events that shape the characters and their circumstances. This use of time travel within a narrative enriches the storytelling and enhances the emotional impact on the audience, making C the correct choice.

The other options do not encapsulate the essence of a flashback. A long dialogue explaining background may provide context but does not involve a shift in time. A current event with consequences reflects ongoing action rather than a return to the past, and a dream sequence may explore a character's thoughts or feelings but does not serve the same narrative purpose as a flashback.
