How does a round character differ from a flat character?

A round character is best defined by their complexity and the capacity for growth throughout a narrative. These characters are typically well-developed, exhibiting a range of emotions, motivations, and personal traits that make them relatable and realistic. They often face internal conflicts or undergo significant changes as the story progresses, highlighting their depth and adding layers to the narrative. This complexity allows readers to understand their experiences and transformations, making them memorable and impactful within the story.

In contrast, flat characters are usually one-dimensional and tend to embody a single trait or characteristic. They do not experience significant change, which makes them less engaging for the audience. The other options compare the nature of the characters incorrectly or misrepresent the characteristics of flat characters. Thus, the definition of a round character as one that is complex and capable of growth establishes a clear distinction from flat characters, which remain static and lack depth.
