Answer: (C)

This item is testing your knowledge of which USPS service uses PS Form 153 and Label 315: Signature Confirmation. This service adds a requirement that the recipient sign for the mailpiece and provides a verifiable proof of delivery. The form and label are used to mark the item so the carrier knows to obtain a signature at delivery and to record the signer’s information and delivery date. It creates a tangible record that the item was delivered to someone authorized, which is why it’s distinct from services that don’t involve a signature or use different forms and labels. The other options refer to services that either rely on basic tracking without a signature, or have their own separate processing and forms.
