What term refers to the center of interest or attention in a narrative?

The term that refers to the center of interest or attention in a narrative is indeed "focus." In literary analysis, focus is key to understanding what the narrative centers around, guiding the reader’s attention toward the main ideas, characters, or events that are most significant in the story.

The focus functions as a lens through which the narrative unfolds, emphasizing particular aspects that shape the reading experience. This term highlights the most critical elements in the story, allowing readers to grasp the main point or core of the narrative effectively.

In contrast, other choices refer to different aspects of storytelling. The theme relates to the underlying message or the central idea explored in the narrative. The plot outlines the sequence of events and actions that take place in the story. The setting establishes the time and place where the narrative occurs. While these elements are essential to a narrative, the focus specifically centers on where the attention of the narrative is directed, making it the most accurate answer to the question presented.
