Which set of records filed consecutively on a shelf displays terminal digit filing order?

• A. 57-78-01, 57-78-00, 56-78-99
• B. 56-78-99, 57-78-01, 57-78-00
• C. 57-78-00, 57-78-01, 56-78-99
• D. 57-78-00, 56-78-99, 57-78-01

Answer: (C)

Terminal digit filing orders records by the trailing digits of the file number, using those last two digits as the primary key. In this set, the final two digits appear as 00, 01, and 99, which is the proper ascending sequence for terminal digits. The other sequences would place 01 before 00 or 99 before 01, breaking the terminal-digit order. If two records shared the same last digits, you would then compare the preceding digits to break the tie, but that isn’t needed here.
