Which of the following best describes the function of foreshadowing?

Foreshadowing serves the primary function of building suspense about future events in a narrative. This literary device hints at what is to come, enticing readers to anticipate how the plot might unfold. By providing subtle clues or indications, foreshadowing can create tension and intrigue, drawing the audience deeper into the story. This technique not only prepares readers for future developments but also enhances their engagement, as they become invested in deciphering the implications of these hints.

The other options, while important in their own right, do not capture the specific essence of foreshadowing as effectively. Developing subplots relates more to the structural elements of the story, while creating emotional responses usually involves different narrative techniques, such as character development or imagery. Meanwhile, explaining backstory focuses on providing context for the characters and events, which does not align with the anticipatory nature of foreshadowing.
