The correct answer is D. Whenever I went to the library, I would see him buried under a mountain of paperwork.
Explanation:
The hyperbole is a figure of speech in which one feature, situation or idea is exaggerated to emphasize it or convey complex meanings. This occurs in poems and literary texts but also everyday language, indeed hyperbole is one of the most used figures of speech. This is illustrated in "Whenever I went to the library, I would see him buried under a mountain of paperwork" because the speaker uses exaggeration through the words "mountain of paperwork" to emphasize the amount of paperwork, despite there is not a literal mountain.
