129- For students of a city from elementary school up to twelfth grade, a five-digit number is assigned as follows: the first two digits on the left represent the educational level (from 01 to 12), the next two digits represent age (from 07 to 18), and the fifth digit represents gender (1 for boy and 2 for girl). Then the numbers are arranged in ascending order in a set. The age is a member of the set. (It is possible that a five-digit number is not assigned to any individual, but it is still counted.) Which of the following is the number of elements of set $A$? (1) $13$ (2) $14$ (3) $15$ (4) $16$
