Which definition best describes a novel?

A novel is best described as an extended work of fiction because it typically features a complex narrative structure, character development, and plot progression that unfolds over a longer format than shorter fictional works, such as short stories or novellas. Novels often explore themes and ideas in depth, allowing for a more immersive experience for the reader. The length and detailed storytelling differentiate novels from brief works of fiction, collections of poetry, or factual accounts. While those other forms may have their own literary purposes, they do not encompass the characteristics that define a novel.
