The correct option is D
Alliteration is the repetition or repetition of similar sounds (phoneme) in a text or literary fragment, as for example in the verse by Rubén Darío "with the aleve wing of the slight fan". This rhetorical or diction figure seeks the sound effect and the expressivity, produced by the consecutive repetition of the same phoneme, or of similar phonemes, vowel or consonant, in a sentence or in a verse, as the DRAE observes in a second meaning of the finished.
The alliteration is not subject to metric norms, for that reason some theoreticians of the Castilian language do not consider it 'rhythmic element in the versification', but simple stylistic resource. In tonal languages it works as a repetition of a sound at least twice in a minor art verse, or at least three times in a major art verse.
