Show answer & explanation
Correct answer: C
The BIOS boot sequence begins with the Power-On Self-Test (POST) to verify hardware integrity. Next, it locates and loads the boot loader into main memory. Finally, the boot loader initializes the rest of the operating system kernel and drivers. Based on this standard sequence, Option 2 (5, 2, 4, 1, 3) is the correct answer.
