A. B. C. D. E.D.
The correct answer is D. mount /dev/sdb1 /data/drive0
Explanation: The output given shows that the device /dev/sdb has a partition /dev/sdb1 with the Linux filesystem (identified by the partition type 83). To make the partition available under /data/drive0, the technician needs to mount it using the mount command.
The mount command syntax is as follows: mount [options] device_name mount_point
In this case, the device name is /dev/sdb1 and the mount point is /data/drive0. Therefore, the command to make the partition available under /data/drive0 is: mount /dev/sdb1 /data/drive0
Option A (fdformat) is incorrect because it formats a disk and cannot be used to mount a partition.
Option B (ext2) is also incorrect because it is not a valid command for mounting a partition.
Option C (net use) is a Windows command and cannot be used on a Linux server.
Option E (fdisk) is used to partition a disk and list the partitions, but cannot be used to mount a partition. The correct option would be to use the mount command as explained above.
