Which of the following best describes 'tragic flaw' in a character?

The concept of 'tragic flaw' refers specifically to a weakness or limitation in a character that ultimately contributes to their downfall. This flaw is often integral to the narrative, illustrating how the character’s inherent traits or decisions lead them toward a tragic conclusion. The tragic flaw serves to highlight the vulnerability of human nature, making characters more relatable and their stories more impactful.

In literature, authors often use this concept to deepen the complexity of their characters and create a sense of inevitability regarding the tragic events that unfold. It’s crucial to understand that this flaw is not only what leads to failure but also reflects the complexity of the character's persona, allowing audiences to explore themes of hubris, ambition, and moral ambiguity.

The other options do not encapsulate this idea effectively, as success and admiration take the focus away from the darkness inherent in a tragic flaw, and an unchanging characteristic does not align with the dynamic nature of characters in tragic narratives.
