The correct answer is B. The author includes a metaphor.
Step-by-step explanation:
In writing, figurative language refers to the use of devices such as metaphor, simile, allegory, metaphor, hyperbole, symbol, etc that do not follow the convention of language in terms of definitions as words and expressions are used to convey different meanings to the conventional ones. Considering this, the example that shows an author's decision to use figurative language is "The author includes a metaphor" because in metaphor one concept or idea is used to named another and therefore words do not follow conventional meaning but are part of figurative language.
