The correct answer is C. Exact rhyme
Step-by-step explanation:
In poetry, rhyme occurs as there is a repetition or recurrence or similar sounds. Additionally, rhyme can be classified into multiple types including slant rhyme, exact rhyme, eye rhyme, internal rhyme, etc. In the case of exact rhyme, this occurs as the final vowel and consonant that follow the sound vower have the same sound in two or more words. This can be seen in the final word from line 2 and line 4 "sane" and "chain" as these words share the same sound including a vowel sound and the consonant sound of "n". Thus, line 2 and 4 are an example of exact rhyme.
