The DDATE rule is a due date sequencing rule, where each job has a specific due date by which it must be completed. The jobs are sequenced in ascending order of their due dates.

The due date for each job in this problem is as follows:
- Job E: Due date = 15 (Today's date + 15) 
- Job A: Due date = 18 (Today's date + 18)
- Job B: Due date = 20 (Today's date + 20)
- Job D: Due date = 25 (Today's date + 25)
- Job C: Due date = 30 (Today's date + 30)

Sequencing the jobs according to the DDATE rule would result in the following order:
E -> A -> B -> D -> C

The tardiness for each job would be as follows:
- Job E: 26 - 15 = 11
- Job A: 29 - 18 = 11
- Job B: 31 - 20 = 11
- Job D: 36 - 25 = 11
- Job C: 41 - 30 = 11

Therefore, the maximum job tardiness would be 11 days, and the best choice is C.
