B or C, but I lean toward B here since specifying
video codec h264 seems required for supporting a video stream. C is tricky, but usually pass-through is audio default. Open to being corrected.C imo. The
codec pass-through command is what actually allows the media resource to handle video streams in Cisco configs like this. A just limits hardware sessions, and B only specifies a codec type (doesn't enable video). D is about associating an app, not specifically handling video streams. Pretty sure C is right unless someone has seen a lab where it works differently.C tbh. A looks tempting but it's a common trap, only C enables media passthrough for video in these configs.
C
Saw similar on the official guide. Practice labs helped reinforce this type of config.
