Which phrase is an example of alliteration?

Alliteration is a literary device characterized by the repetition of the initial consonant sounds in a series of words. This technique enhances the musical quality of language and can create rhythm and mood in poetry and prose.

In the chosen phrase, "She sells sea shells by the sea shore," the repetition of the "s" sound in "she," "sells," "sea," "shells," and "shore" exemplifies alliteration. This repeated sound draws attention to the phrase, making it catchy and memorable, which is often why such phrases are used in tongue twisters and children's literature.

The other options contain different literary devices. While "Time flies like an arrow" features a simile, "The bed is a mess" is a straightforward statement without sound repetition, and "The leaves danced in the wind" uses imagery and personification rather than alliteration.
