Why each option

To recover a failed RAID 1 disk after replacement, array management utilities are used to rebuild and synchronize data from the healthy disk to the new drive.

ATape restore utilities

Tape restore utilities are used to recover data from tape backups, which is a full data restore operation rather than rebuilding a disk within an active RAID array.

BImaging utilities

Imaging utilities create or restore full disk images, which is a broader data recovery method and not the direct tool used to rebuild a disk within an operational RAID 1 array.

CPartitioning utilities

Partitioning utilities are used to create, delete, and manage disk partitions, which is a preparatory step for a drive but does not manage the RAID array's data synchronization or rebuild process.

DArray management utilitiesCorrect

Array management utilities are specifically designed to manage RAID configurations, including monitoring array health, replacing failed drives, and initiating the rebuild process for redundant arrays like RAID 1. These utilities read data from the healthy mirrored disk and write it to the newly installed drive to restore redundancy.
