Corresponding though channels, you list interested addressees in the _____ block when they need to see a memorandum before it reaches the action addressee.

• A. To
• B. Thru
• C. Cc
• D. Subject

Answer: (B)

In official memoranda, those who must see the document before it reaches the person who acts on it are listed in the Through block. This block shows the chain of review or coordination required as the memo moves up or down the command, ensuring the necessary intermediaries have the opportunity to review, raise issues, or approve before the action addressee receives it. The other blocks serve different purposes: To is for the primary recipient who will take action, Cc is for informational copies, and Subject states the topic. By putting interested addressees in the Through block, you make the routing clear and ensure proper oversight as the memorandum progresses.
