Explanation
Correct answer: A.
Choice A is the best answer. "To be exact" logically signals that this sentence about the Coastal Virginia Offshore Wind project plan provides specific, precise details—number of turbines, location of site—elaborating on the more general information about the project in the previous sentence.
Why the other choices are wrong
Choice B
Choice B is incorrect because "in conclusion" illogically signals that the information in this sentence about the Coastal Virginia Offshore Wind project plan concludes or summarizes the discussion of the project in the previous sentences. Instead, the sentence provides specific, precise details elaborating on the previous information.
Choice C
Choice C is incorrect because "as a result" illogically signals that the information in this sentence about the Coastal Virginia Offshore Wind project plan is caused by, or occurs as a result of, the information about the project in the previous sentence. Instead, the sentence provides specific, precise details elaborating on the previous information.
Choice D
Choice D is incorrect because "in contrast" illogically signals that the information in this sentence about the Coastal Virginia Offshore Wind project plan contrasts with information about the project in the previous sentence. Instead, the sentence provides specific, precise details elaborating on the previous information.
