Suggested Answer: C 🗳️
A kernel panic is a type of error that occurs when the core (kernel) of an operating system receives an instruction in an unexpected format or when it fails to handle properly. A kernel panic can also follow when the operating system cant recover from a different type of error. A kernel panic can be caused by damaged or incompatible software or, more rarely, damaged or incompatible hardware.
When a server kernel panics it abruptly halts all normal system operations. Usually, a kernel process named panic() outputs an error message to the console and stores debugging information in nonvolitile memory to be written to a crash log file upon restarting the computer. Saving the memory contents of the core and associated debugging information is called a "core dump."
