The correct answer is: A. The author repeats words and employs parallelism.
Indeed, the sentences are structured in a parallel manner with regards to their components. The first sentence includes the subject (the little farmers=they) plus the verb conjugated in simple past tense (watched) and the rest of the predicate. The second sentence is structured almost exactly in the same manner with the exception that the subject is represented by the personal pronoun “they”. The use of anaphora between the second and third sentence is another typical feature of parallelism.
