Which of the following best describes satire?

The definition provided by the correct answer highlights the fundamental aspect of satire. It is characterized by the use of humor, irony, exaggeration, or ridicule to criticize and expose the flaws, vices, or shortcomings in human behavior, institutions, or society at large. Satire serves a dual purpose: it entertains while also provoking thought and reflection on serious issues. This critical examination of human misconduct is what distinguishes satire from mere comedy or entertainment.

In contrast, other descriptions do not capture the essence of satire accurately. Celebrating human achievement does not align with the primary goal of satire, which is to critique rather than glorify. A form of comedy that entertains without critique fundamentally misunderstands satire, as the latter is rooted in social criticism. Lastly, a style of writing that aims to inform readers does not specifically convey the critical and often humorous nature of satire. Instead, satire seeks to ridicule and provoke discussion, making option C the most fitting definition of satire.
