Why each option

The Cisco UCM route pattern 1[23]XX matches any four-digit number that begins with '1', followed by either '2' or '3', and concludes with any two digits.

A1200 through 1300 only

This range incorrectly limits the last two digits to '00' for the '13' prefix, excluding numbers like 1301 through 1399.

B1200 through 1399 onlyCorrect

In Cisco UCM route patterns, 'X' represents any single digit from 0-9, and square brackets '[ ]' indicate a single digit that can be any of the numbers listed within the brackets. Therefore, 1[23]XX means the first digit is '1', the second digit can be '2' or '3', and the last two digits can be any combination from '00' to '99'. This covers numbers from 1200 (1-2-0-0) to 1399 (1-3-9-9).

C12300 through 12399 only

This range has too many digits (five) and does not match the four-digit structure defined by the '1[23]XX' wildcard.

D1230 through 1239 only

This range is too restrictive for the 'XX' wildcard, as it only covers '30' to '39' instead of '00' to '99' for the last two digits.
