Hi, you've asked an incomplete question lacking options. I inferred you want to know the type of literary device or rhetoric used in the sentence.
Answer:
Repetition, and Parallelism
Explanation:
Repetition is a type of literary device that involves the use of a word or phrase several times (repeatedly) in a speech or sentence. While Parallelism involves the use of phrases with grammatical structure, which may create a pattern or rhythm.
For example, in the above sentence, we can observe the repetition of the word, "What", and "be". And the sentence, "Break what must be broken" has a similar grammatical structure as the first sentence.
