In REPEAT mode, if initiated from the rear cockpit, display control inputs from both cockpits communicate with which Integrated Avionics Computer (IAC)?

Explanation:
In REPEAT mode, the control inputs from both cockpits are routed through the primary Integrated Avionics Computer to keep the displays synchronized. When initiated from the rear cockpit, those inputs are sent to IAC1, which serves as the hub for this mode, processing and distributing them so both cockpits see and react to the same actions. IAC2 and IAC3 handle other tasks or act as backups and aren’t the central conduit for REPEAT cross-cockpit inputs. So IAC1 is the correct choice.
