Answer: D) onomatopoeia.
Explanation: a metaphor is a direct comparison without using the words "like" or "as." Alliteration is the repetition of the beginning sound of consecutive words, or words that are close to each other. A simile is also a comparison but using the words "like" or "as." And an onomatopoeia is a figure of speech that consists in creating or using words that include sounds that are similar to the noises the words refer to, for example: cuckoo, meow, honk, boom, etc. So the correct answer is option D.
