Concept:Onomatopoeia is a figure of speech in which the sound of a word echoes and reinforces its meaning.
Explanation:Look closely at the words in the quoted sentence to check whether their pronunciation imitates the action or object they describe.
When the spoken sound of the word suggests what it means, the sentence is using onomatopoeia.
This device makes the expression more vivid because the reader can almost hear the sound represented by the words.
It does not rely on comparison, unlike metaphor or irony, but purely on the effect of sound suggesting sense.
Since the expression in the question matches this sound-meaning pattern, the figure of speech being used is onomatopoeia.
Answer:A. onomatopoeia.
