Which of the following best describes an aphorism?

An aphorism is best described as a witty statement of truth because it succinctly expresses a general principle or observation about life, often with a clever twist. These statements are typically memorable and resonate with readers due to their insightfulness. Famous examples include sayings like "The early bird catches the worm" or "A penny saved is a penny earned," which encapsulate wisdom in a brief and impactful manner. This concise delivery and the blend of wit with meaningful truth are what define aphorisms, making option C the most accurate descriptor.

In this context, the other choices do not align with the characteristics of an aphorism. A lengthy narrative suggests a more extended and detailed form of storytelling, which is contrary to the concise nature of an aphorism. A rhetorical question, while it may contain an implied truth, does not necessarily provide a wise or witty statement; rather, it seeks to provoke thought or emphasize a point without expecting an answer. A form of poetry refers to structured artistic expression that adheres to specific meter and rhyme, which is distinct from the bite-sized nature of an aphorism.
