Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The kernel is the core part of an operating system that remains in memory (RAM) at all times, managing CPU, memory, and hardware resources. The registry is a Windows configuration database, API is an interface for applications, and CMOS is BIOS configuration memory on the motherboard. The kernel is always memory-resident because it must handle every system call and hardware interaction. Terms like 'resident' mean staying in memory continuously.
