What is a simile?

A simile is a figure of speech that makes a direct comparison using 'like' or 'as', which is exactly what option B states. It effectively highlights similarities between two different things, allowing readers to visualize ideas or concepts more vividly. For example, saying "as brave as a lion" draws a direct line between the qualities of bravery in a person and the well-known bravery of a lion, creating a strong image for the reader.

The other options do not accurately describe a simile. A phrase that equates two different things with the word 'and' does not illustrate a comparison using 'like' or 'as', which is fundamental to the definition of a simile. Describing an author’s word choice and structure refers to broader literary concepts rather than a specific figure of speech. Lastly, a style of writing that incorporates sarcasm and irony describes a tone or approach rather than a simile itself. Therefore, option B is indeed the correct choice.
