The best opening sentence for such a business/informal letter is B. Your order of February 10 arrived in our office today. This is the only sentence that doesn't sound too formal and use a bunch of fancy words in order to make it seem more formal, which is the reason why it is the least formal, in this case and thus the correct answer.
