B.
System is down and running.

C.

Explanation:
This is true, since RAID 5 uses parity to provide fault tolerance through the array,
once of the disk in it can become corrupted, and you usually can just take it out without turning off
the system (Hot SWAP) and plug a spare disk on the bay. Then the array will automatically begin
to reconstruct the information in the new disk with the parity contained through the other disks in
the array. This Hot Swap capability is usually present in enterprise servers that require high
availability.
