DDATE stands for Due Date and this rule sequences the jobs in the increasing order of their due dates.

By sequencing the jobs using the DDATE rule, we get the following order:
Job 2 -> Due date: Day 7 -> Tardiness: 9 days
Job 1 -> Due date: Day 9 -> Tardiness: 7 days
Job 3 -> Due date: Day 13 -> Tardiness: 3 days
Job 4 -> Due date: Day 18 -> Tardiness: 0 days

So, the maximum job tardiness is 16 days (Job 2), which is option C.
