Q__6

C. Mount the drive in the carrier, connect the master drive after the twist in the cable, connect the slave drive before the twist in the cable, install the drives in the computer, and configure the drives.
D. None of the above.

A: The sequence is plausible except that it does not make provision for the installation of master and slave drives.
C: The sequence is not correct since you need to first mount the drives in the carrier, then connect the cable to the drives and not as suggested by this option.
D: This is irrelevant. You got to have a basic sequence to install drives.
