It's a stu[id question from Salesforce, It's not specified here how does the trigger of the process is configured, As per the salesforce doc :
- For processes that start when a record is created or edited:
Actions remain scheduled only as long as the criteria for the actions are still valid. If a record no longer matches the criteria, Salesforce cancels the scheduled actions for the record.
If the referenced field value changes, and the schedule hasn’t been processed, Salesforce recalculates the scheduled time for the actions using the updated field value.
For example, a process emails an opportunity owner 7 days before the opportunity close date. The close date is set to 2/20/20XX, and Salesforce schedules the email to be sent on 2/13/20XX. Before the email is sent, the close date is updated to 2/10/20XX. Salesforce recalculates the scheduled time and schedules the email to be sent on 2/3/20XX.

- For processes that start when a record is created, Salesforce never reevaluates the record associated with that process. The scheduled time for the actions stays the same, even if the record no longer meets the associated criteria when the scheduled actions are executed.

The answer is B, if the process is configured to be triggered on Create/Update
The answer is D, if the process is configured to be triggered on Create...

The correct answer is B.

D: No, it will not be sent as the posting status is updated to interviewing
