Answer: A. Alliteration.
Step-by-step explanation: Alliteration is the repetition of similar sounds at the beginning of consecutive words, or words that are close to each other. Alliteration is often used to create a musical effect on a poem, and to make the reading experience more appealing. The given phrase is a clear example of alliteration, because we can see the repetition of the sound "cr" in the words "cruel," "crazed" and "crones."
