Which of the following best describes 'unique' in literary terms?

In literary terms, 'unique' refers to something that is one of a kind or distinct. This concept is fundamental to understanding how authors create their narratives, characters, and themes. When a story, character, or style is described as unique, it highlights its originality and the distinctive features that set it apart from other works. For example, a unique character may possess specific traits or experiences that make them stand out, while a unique narrative style can offer fresh perspectives that engage readers in innovative ways.

The other options address different literary aspects. The idea of a common theme pertains to recurring motifs across literature, which does not capture the essence of being unique. A narrative technique implies specific strategies to develop plot or tension, rather than the individuality of a piece. Character development processes focus on the evolution of characters, which may or may not convey uniqueness in their traits or story arcs. The term 'unique' specifically emphasizes singularity and distinction, making the first choice the most accurate description in this context.
