Answer:
C). Parallelism.
Step-by-step explanation:
'Parallelism' is demonstrated as the literary device that involves repetition of words, or phrases with similar or parallel grammatical structure, meter, or sound, etc. It allows the author to propose a pattern as well as a rhythm that promotes the smooth flow of ideas and enhance its persuasiveness.
In the given passage from 'The Grapes Of Wrath', the author employs 'parallelism' which is reflected through the repetition of the phrase 'could not', 'the land', etc. that offers a balance and rhythm to it. It allows the smooth transition of ideas and enhances the understanding and persuasiveness for the readers. Therefore, option C is the correct answer.
