What distinguishes young adult literature from other forms of literature?

Young adult literature is characterized by its focus on protagonists who are at an age and emotional stage similar to that of its readers, typically involving experiences associated with adolescence. This close emotional and temporal connection means that the characters often face challenges, dilemmas, and experiences that resonate strongly with young adults—things like identity exploration, friendships, family relationships, and the journey toward independence. This relatability is what draws young readers to these stories and allows them to see their own lives reflected in the narratives.

The other options, while they may apply to some young adult literature, do not define the genre in the same way. Complex narrative structures and adult themes can also be found in literature aimed at adult audiences, and a focus on historical accuracy, though it may be present, is not a defining trait of young adult literature. The essence of this genre lies in its ability to authentically portray the teenage experience, making option B the distinguishing feature of young adult literature.
