All of the options provided describe literary techniques, but they focus on different aspects of the author’s style. Here’s a breakdown:
A. Onomatopoeia enhances the description of bees by mimicking sounds, effectively conveying their activity. B. An extended metaphor creates a deeper comparison between the Limberlost and other swamplands, enriching the imagery. C. Subtle personification gives human-like qualities to the frogs, emphasizing their experience and connecting readers to their perspective. D. Alliteration emphasizes sounds through repeated consonants, creating a rhythmic effect that can enhance imagery.
Each choice represents a literary technique. If you are looking for a specific answer regarding which technique is employed by the author, any of these descriptions could fit depending on the context of the text in question. If the question intends for you to identify a singular technique used prominently, that would depend on specific examples from the text being analyzed.
