Which of the following BEST describes kernel panic?
The correct answer is C. A low-level OS function that handles any fatal errors by sending an image of the system's.

Explanation
A kernel panic is a safety mechanism in Unix/Linux-based operating systems (analogous to the Windows Blue Screen of Death/BSOD) that occurs when the kernel detects an unrecoverable fatal error. The OS halts all operations and generates a crash dump-an image of the system's memory state at the time of failure-to assist with post-mortem debugging. Choice C correctly identifies this as a low-level OS function handling fatal errors by capturing a system image. Option A describes a boot override, B incorrectly ties it to rootkit detection, and D describes a priority inversion problem-none of which accurately define kernel panic.
