The figure of speech that uses repetition of a specific consonant sound at the beginning of words or syllables is called alliteration. So, option D is correct.
Alliteration refers to the repetition of identical initial consonant sounds in successive or closely associated syllables within a group of words, even those spelled differently. Alliteration is also called head rhyme or initial rhyme.
Example of alliteration: "Peter Piper picked a peck of pickled peppers".
