Which statement about the header is true?

• A. It is handwritten in a casual font.
• B. It includes only the subject line.
• C. It consists of two or three lines with organization and address on official letterhead.
• D. It is optional if memo is internal.

Answer: (C)

The header identifies who is sending the memo and where it’s coming from, using official letterhead. In professional military/public health communications, the header sits on official letterhead and includes the organization and address, helping the reader quickly verify the source and know where to contact the sender. A typical header is two or three lines long and follows the organization’s standard formatting, establishing authority and consistency across official paperwork. This matters because it provides immediate context and accountability for the document, and it’s the standard that keeps internal communications professional and traceable. Handwritten casual fonts fail to convey formality, a header isn’t just the subject line, and it isn’t optional for internal memos—proper header information supports credibility and record-keeping.
