Which line is used to substitute for the To line when there are multiple addressees?

• A. The first line below the enclosure line
• B. The second line below the enclosure line
• C. The third line below the enclosure line
• D. The top line above the enclosure

Answer: (B)

In official naval correspondence, when there are multiple addressees you don’t crowd the To line; a specific line is used to indicate the recipients. The line that substitutes for the To line when there are several addressees is the second line below the enclosure line. This placement keeps the header structure clean and makes it clear who should receive the message, while the enclosure notation remains in its standard spot. The other lines in the header serve their normal purposes and aren’t designated for listing multiple addressees, so they aren’t used for this substitution.
