What is a 'synopsis' best defined as?

A 'synopsis' is best defined as a plot summary because it typically provides a concise overview of the key elements of a narrative, including the main characters, setting, and overall storyline. A synopsis aims to give the reader a clear and brief understanding of what the story is about without going into exhaustive detail or interpretation. This focus on summarization aligns well with the common use of the term in literature, film, and other media to give potential readers or viewers a quick insight into the content. The other options suggest a depth of analysis or critique that goes beyond the purpose of a synopsis, which is inherently about summarizing rather than critically engaging with the material.
