Final answer:
The condition for time of service to arise out of the same T/O and not require adding one without JX is that time of service does not require adding one without JX.
Step-by-step explanation:
The correct condition for time of service to arise out of the same T/O and not require adding one without JX is option 4) Time of service does not require adding one without JX.
When time of service is related to the same T/O, it means that it is associated with the same time-off period. In this case, adding one without JX is not necessary.
For example, if an employee takes a vacation day and then continues working after the vacation without any break in service, the time of service does not require adding one without JX.
