The chosen sentence is punctuated correctly because it adheres to the standard rules of writing addresses in American English. The name "John Huntington III" is presented accurately without unnecessary punctuation, ensuring clarity when reading the name and designation.

Additionally, the address includes the city and state abbreviation, which is formatted correctly as "New York, NY." In this case, "NY" is the accepted two-letter postal abbreviation for New York, and using a comma after the city is appropriate. The ZIP code "02138" follows, completing the address properly.

Overall, this construction maintains a logical and consistent format throughout, facilitating easy comprehension while meeting grammatical conventions. Other options either misplace commas or incorporate inconsistent or incorrect formatting, making them less appropriate for proper punctuation in this context.
