Answer:
C. A refrain
A refrain is a line or a verse that appears at the end of a stanza. It is usually repeated in every, or several, stanzas. The repetition of the phrase at regular intervals contributes to the rhyme of the poem. It also makes it more persuasive by emphasizing a particular idea through repetition.
B. internal rhyme
An internal rhyme is one that occurs within a single line of verse. This is different to the end rhyme, which appears at the end of different lines. In this case, the words "peering" and "fearing" are an example of an internal rhyme.
