Step-by-step explanation:
The young boy's experience of moving to a new town and struggling to fit in is best depicted by the genre of realistic fiction. This genre, which focuses on believable characters and situations that could occur in real life, often explores themes such as personal growth, everyday challenges, and social interactions. Unlike historical fiction that relies on historical backdrops or mystery and fantasy that involve elements of suspense or supernatural occurrences, realistic fiction concentrates on relatable, true-to-life experiences.
