Question: What action does an SC (Short Message Service Center) take when it receives a TP-Command to Delete a previously submitted short message, and the original Submit SM request had requested a Status Report?
Option 1: The SC sends an RP-Error with a TP-Failure-Cause indicating "Message Not Found"
Option 2: The SC silently deletes the message without sending any report.
Option 3: The SC returns an RP-ACK confirming the deletion but does not send a Status Report.
Option 4: The SC sends a Status Report indicating that the SM (Short Message) has been deleted.
Explanation: According to the specified behavior for TP-Command handling, when the SC is instructed to delete a previously submitted short message and the original submission requested a status report, the SC must send a Status Report confirming the deletion. This ensures transparency and feedback on the outcome of the deletion request, aligning with the initial request's specifications.
