In literature, what does the term "argument" often refer to?

In literature, the term "argument" typically refers to a set of opposing viewpoints in a debate. This means that writers often present conflicting perspectives or ideas within their texts, allowing for a discussion or exploration of different sides of an issue. This can enhance the complexity of the narrative and invite readers to engage critically with the material. It allows for the exploration of themes such as conflict, morality, and human behavior as characters argue or debate their beliefs and motivations. This engagement with differing viewpoints can provide depth to the literary work, making it richer and more thought-provoking.

The other options, while they pertain to aspects of literature, do not encapsulate the essence of what "argument" signifies in a literary context. Character development and techniques for plot advancement relate to how characters evolve or stories unfold, rather than the concept of argument itself. A description of the main theme focuses on the overarching message of the work but doesn't directly align with the idea of presenting opposing ideas or viewpoints.
