In abbreviated plain dress messages, which format line is additionally mandatory beyond 2,4,11,12,13,15?

• A. Line 16
• B. Line 9
• C. Line 10
• D. Line 14

Answer: (A)

In abbreviated plain dress messages, there is a fixed sequence of lines that carry essential metadata and routing information, so the message can be parsed and acted on quickly. Beyond the lines already required, there is one more line that must be included to provide a definite closing element and a point of contact for follow-up. This final line serves as the formal end of the message and ensures the originator’s identity or authority and a way to reach them, which is crucial for verification, accountability, and proper routing by automated systems. Without it, the message could be ambiguous or delay action. That’s why the additional mandatory line is the last line in the format. The other options don’t fit because they would disrupt the standard ending or fail to supply the necessary closing and contact information, which the final line guarantees.
