Answer:
A. assonance
Step-by-step explanation:
I will begin by defining the meaning of each term before answering the question just to have an insight
Assonance can simply be define as a repetition of similar vowel sounds in a sentence
Consonance : Just like assonance, consonance is the repetition of similar consonant sound in a sentence
Alliteration is a special case of a consonance . It is a repetition of similar consonant sound at the beginning of words in a sentence
Repetition is simply an act of repeating the same words or sentence in a speech, poetry etc
From the above definition, we can now deduce that "end in madness" is an example of assonance, it involves the repetition of the vowel sound "e" in the two words; end and madness
