Final answer:
The sentence 'She will take the job offer in either Boston or Atlanta' correctly uses the correlative conjunctions 'either' and 'or' to express a choice between two options while maintaining parallel structure. The correct option is (b).
Step-by-step explanation:
The correct sentence that uses correlative conjunctions correctly is: She will take the job offer in either Boston or Atlanta. Correlative conjunctions are pairs of conjunctions that work together to coordinate two items. In this case, the conjunctions 'either' and 'or' are used to provide a choice between two options. When using correlative conjunctions, it is important to ensure parallel structure, which means that the elements presented by the conjunctions should be similar in construction.
