Answer:
2. Then the blue foxes and the yellow flongboos pattered pitty-pat, pitty-pat, each with feet and toenails, ears and hair, everything except tails, patter scritch scratch over the stone floor out into the train shed.
Step-by-step explanation:
Onomatopoeia is the use of words to express the sound it makes. It is the formation of words through the sounds heard, like "buzz, crack, hiss, swoosh, boom, gurgle, mumble," etc. Such terms that are the same as the sounds they make are known as onomatopoeic words.
In the given excerpts, the one that uses onomatopoeia is the second option. The words "pitty-pat, pitty-pat" and "patter scritch scratch" are onomatopoeic, for they are the sounds that are produced by the "feet and toenails, ears and hair". The other sentences don't contain any onomatopoeic sounds or words.
Thus, the correct answer is option 2.
