How does the author use humor in the story?

The correct choice highlights how humor is employed to lighten the narrative and showcase Enzo's personality. In "The Art of Racing in the Rain," Enzo, the dog who narrates the story, has a unique perspective on human life, which often leads to humorous observations and insights. His witty commentary and the way he interprets human behaviors provide levity to serious themes, making the story more accessible and engaging for the reader.

By infusing humor into the narrative, the author creates a balance between the poignant moments and more lighthearted ones, allowing Enzo's character to shine through as relatable and endearing. This not only makes the narrative enjoyable but also deepens the emotional impact as readers connect with both the humor and the underlying serious messages about life, love, and resilience.
