Final answer:
Star codes such as *67 or *82 are used for call blocking features, not for recording calls. Recording calls typically requires consent, and no standard star code exists for this purpose. The star code listed as an answer option is not valid for recording a call.
Step-by-step explanation:
The question asks about a specific star code used for recording phone calls. Unfortunately, recording a call using a star code is not a standard feature inherent to phone services, and it would actually be illegal in many jurisdictions without the consent of both parties on the call. The codes listed, such as *55, *67, and *82, generally have other functions like blocking caller ID or unblocking it, and not for recording calls. *15 is not a recognized star code for recording or other features.
