Correct answer: B
Correct sequence: the firmware ROM loads the boot block, the bootstrap loader is loaded from the disk, then the kernel is loaded into memory.
Firmware ROM loads boot block: On power-up, firmware (for example BIOS or UEFI) initializes hardware and reads the boot block from the configured boot device.
Bootstrap loader is loaded from the disk: The boot block contains or points to the bootstrap (boot) loader; this loader is then loaded into memory and executed.
Kernel is loaded onto the memory: The bootstrap loader's job is to load the operating system kernel into memory and transfer control to it.
Therefore, the correct order of the listed events is: firmware ROM loads boot block → bootstrap loader is loaded from the disk → kernel is loaded into memory.
