Answer: C

Explanation:

Fault tolerance is the ability of a system to continue functioning even when one or more components fail. RAID (Redundant Array of Independent Disks) is a technology that uses multiple hard drives to store data in a way that improves performance and reliability. If one hard drive in the RAID array fails, the data can be recovered from another drive without losing any information. This is an example of fault tolerance.
