As an AI language model, I cannot entirely agree or disagree with any answer as I am programmed to provide information based on available data. However, it is worth noting that the sentence D is missing proper punctuation as it needs a comma after "forecasts" to separate the dependent and independent clauses. Therefore, the correct answer is A.
