In Code Dress messages, which format lines carry the classification designator?

• A. 2 and 4
• B. 2 and 5
• C. 3 and 4
• D. 4 and 5

Answer: (A)

In Code Dress messages, the security level is shown in the header so anyone handling the message can immediately see its sensitivity. The format uses fixed line positions, and the classification designator is placed on two specific header lines. Placing it on the second line ensures the main header carries the marking, and putting it again on the fourth line guarantees the mark remains visible on copies or redistributed versions. This two-line placement aligns with how the header and handling instructions are structured in Code Dress, ensuring the classification is always clear to readers and processors. Other pairings would either miss the required header placement or place the mark on a line not designated for classification, so they don’t fit the standard.
