D) Fault tolerance is a risk management concept in which operations continue in some capacity despite a failure.
Adaptation to non-critical failure alludes to the capacity of a framework (PC, organization, cloud bunch, and so on.) to operate without interruption in the event that one or more of its parts fail.
To put it another way, fault tolerance is the way an operating system (OS) handles and allows for hardware or software failures and malfunctions. Hardware, software, or a combined solution utilizing load balancers can be used to manage an OS's ability to recover from and tolerate faults without failing.
