Which of the following best defines "travesty"?

The term "travesty" best aligns with the definition that describes a comedy characterized by broad satire and improbable situations. In literature and theater, a travesty often involves a distortion of serious works, turning them into humorous parodies that exaggerate their flaws and absurdities. This comic form takes serious subjects and presents them in a ludicrous manner, thus providing social commentary or critique through humor.

The other choices do not encapsulate the essence of "travesty." A serious tragedy, a historical event, and a logical argument all lack the comedic and satirical elements that define a travesty. Instead, they align more closely with somber or factual topics rather than the humorous and often exaggerated nature of a travesty in a comedic context.
