A. Parallelism.

Explanation:

A rhetorical technique is the use of language by writers in such a way to make their stories or texts more persuasive and enhance the arguments or more color. These techniques include alliteration, repetition, imagery, parallelism, personification, etc. among others.

In the given passage from John Steinbeck's "Grapes of Wr ath", the writer used the rhetorical technique of parallelism. Parallelism is when there is a form of repetition, similarity in the structure, and use of certain words in the sentence.

The use of "a tw itch in the controls", "could not tw itch because the m o ns ter that built the tractor", "the mo n st er that sent the tractor", "go ogled him and mu z z led him- go og led his mind, mu zzl ed his speech, go o gled his perception, mu z zl ed his protest" are all forms of parallelism in the passage.

Thus, the correct answer is option A.
