Which of the following is a Mailing Service?

• A. Priority Mail Express
• B. Bound Printed Matter
• C. Parcel Return Service
• D. Parcel Select

Answer: (B)

The key idea here is that a Mailing Service refers to a category used to describe how mail is prepared and priced for sending, especially for items that are mailed rather than shipped as packages. Bound Printed Matter fits this because it’s a specific mail rate category for printed materials that are bound together—think magazines, catalogs, newspapers, and other bound printed matter. It allows lower postage rates for items of this type when mailed, which is why it’s considered a mailing service. The other options describe delivery or handling methods for packages (fast delivery, returns, or ground shipping) rather than a mail-rate category for printed items, so they don’t fit the concept of a mailing service in this sense.
