Which element is part of Aristotle's concept of tragedy?

One of the key elements of Aristotle's concept of tragedy is "peripeteia," which refers to a sudden reversal of fortune or change in circumstances, particularly in a way that leads to the protagonist's downfall. This element is crucial to the structure of a tragic narrative, as it highlights the contrast between the character's previous state of happiness or stability and the ensuing disaster.

Peripeteia exemplifies Aristotle's belief that tragedy should invoke pity and fear in the audience, as they witness the protagonist's fall from grace due to a reversal of fortune, often stemming from a critical flaw or error in judgment. This element of unexpected change is what makes a tragic story compelling, drawing the audience into an emotional experience.

While the other choices may relate to elements of storytelling, they do not specifically capture the essence of tragedy in the way peripeteia does. For instance, the climax is a critical moment in the plot progression, while confusion and denouement pertain to the narrative structure but do not encapsulate the fundamental aspect of tragic reversal as defined by Aristotle.
