Explanation

A bootloader (such as GRUB2) is responsible for finding and loading the operating system kernel into memory to begin the OS startup process. It can present a menu of available kernels or OS entries and pass control to the chosen kernel. Option A (initializing devices) is performed by the system firmware (BIOS/UEFI) before the bootloader runs. Option B (mounting the root filesystem) is performed by the kernel itself after it loads, or by the initramfs/initrd. Option D (starting system services) is the responsibility of the init system (e.g., systemd) after the kernel has already taken over.
