What is a universal theme best defined as?

A universal theme is an idea that resonates with people across a wide range of backgrounds, cultures, and experiences. It speaks to fundamental aspects of the human condition and is relevant to everyone, regardless of their diverse circumstances. This is why option A is the correct answer; it emphasizes the broad applicability of the theme in question. Universal themes often touch upon topics such as love, death, conflict, and resilience, which are experiences or emotions that many people can relate to regardless of their specific cultural contexts.

The other options do not align with the definition of a universal theme. A theme that relates only to a particular culture lacks the overarching quality that defines a universal theme, while a concept understood only by a select group is too narrow and exclusive. Additionally, the notion that a theme only exists in literature and is unrelated to real life misses the point entirely; universal themes are intended to connect literature with the larger human experience.
