Answer: A. Alliteration.
Step-by-step explanation: Alliteration is a literary device that consists in the repetition of the beginning sound of consecutive words, or words that are close to each other in a sentence. It is used to create rhythm and symmetry. In the given sentence, we can see a clear example of alliteration, where the sound produced by the letter "w" followed by a vowel or an "h" is repeated in the beginning of almost every word.
