A simile is indeed best described as a comparison that explicitly uses the words 'like' or 'as' to draw a comparison between two different things. This literary device helps create vivid imagery and brings abstract concepts to life by relating them to more familiar terms. For example, saying "as brave as a lion" helps readers visualize the bravery being compared to something universally recognized for its courage.

The other options do not accurately capture the essence of a simile. An implied metaphor, for instance, suggests a comparison without directly stating it, while irony is a rhetorical device that involves a discrepancy between expectation and reality, which is not necessarily a characteristic of similes. Exaggeration in writing falls under hyperbole, which is a different literary device used for emphasis rather than direct comparison. Thus, the correct definition encapsulated in the choice emphasizes the fundamental structure of similes, making it the best answer.
