The correct option is C alliteration
Alliteration means a series of words use the same consonant. Option C)alliteration is correct as repents and recoils start with 'r' and climbs and closes start with 'c'. The other options are wrong as metonymy, exaggeration, and synecdoche mean a representative word which stands for something else, describing something as what it really isn't, and a word which is a term for a part of something but refers to the whole of itrespectively. The correct answer is C)alliteration.
