How can a strong theme enhance a literary work?

A strong theme enhances a literary work by providing a unified underlying message that resonates throughout the narrative. This cohesive message helps to connect various elements of the work, including characters, plot, and setting, creating a rich and meaningful experience for the reader. When a theme is well-developed, it can illuminate the author's intentions and invite readers to engage with deeper philosophical or moral questions, fostering a sense of connection and reflection.

In contrast, the other options do not support the enhancement of a literary work in the same way. Distracting readers from characters would undermine character development and engagement. Limiting the narrative scope could restrict the depth and complexity of the story being told. Complicating the plot structure might introduce confusion rather than clarity, leading to a less impactful reading experience. Therefore, a strong theme serves as a guiding principle that strengthens the overall impact of the literary work.
