What is used to comment on a memorandum in routing?

• A. Signature
• B. Notation
• C. Endorsement
• D. Circulation

Answer: (C)

In routing a memorandum, an endorsement is used to comment. It provides a formal note from the reviewer about what action is taken or needed, such as approval, forwarding to the next person, or returning for additional work. This makes the document’s status and next steps clear as it passes along the routing path. A signature authenticates who is approving, but it doesn’t convey the action or instruction; a notation is a general remark without formal routing action; and circulation refers to moving the document from one person to another, not the comment itself.
