Which of the following literary devices involves comparisons using "like" or "as"?

The correct answer is similes, as this literary device specifically involves making comparisons by using the words "like" or "as." This method creates vivid imagery and connects unfamiliar concepts to familiar ones, enhancing the reader's understanding by drawing parallels. For example, saying "her smile was like the sun" allows the reader to visualize the warmth and brightness associated with a smile by comparing it directly to something known and relatable.

Analogies also involve comparisons, but they typically explain relationships between two different things rather than creating direct imagery. Hyperbole is an exaggeration used for emphasis and does not involve comparison using "like" or "as." An oxymoron consists of contradictory terms placed together, and it does not serve the purpose of comparison either.
