C.Cold site

D.  Hot site

The appropriate option for an organization, like an airline, that cannot tolerate any downtime or any loss of data is:

B.  Real-time mirroring

Explanation:

Real-time mirroring copies data in real-time from one storage device to another storage device. This ensures that the copied data is an exact copy of the data from the original device.   Where office space is needed because of a disaster, a cold site is appropriate. On the other hand, a hot site is a commercial disaster recovery service for continued computer and data processing operations.
