B. social

Explanation:

The excerpt represents a social letter. We can come to this conclusion because the letter has a friendly and easy-to-understand language that retains the "Mr" and "Mrs" titles, which shows that the letter is not informal. Also, the author of the letter is thanking the hospitality of Mr. and Mrs. Brothers and not dealing with business, this shows that this is not a business letter.
