What types of items are categorized under Package Services?

The correct choice encompasses a variety of items that are typically classified under Package Services. This category is designed to accommodate packages that are not strictly letters but can include various forms of merchandise and media. Merchandise refers to goods available for sale, while printed matter includes catalogs, brochures, and other non-personal content, making it a broad classification. Additionally, the inclusion of CDs and DVDs highlights the capability of the postal service to handle items that may require special treatment or packaging due to their physical nature.

Other options fail to capture the full scope of what Package Services include. Some may limit the definition to letters and envelopes, while others might focus on documents or express delivery, which do not represent the complete range of package types that can be shipped through this service. Only option B accurately reflects the diverse array of items categorized under Package Services.
