Which statement about bootloaders is true?

• A. It configures BIOS settings before boot.
• B. It runs antivirus checks during startup.
• C. It loads user applications after the OS starts.
• D. It initiates the boot process and presents OS startup options to the user.

Answer: (D)

A bootloader’s job is to start the boot sequence and present OS startup options to you. It runs before the operating system is loaded, offering choices (such as which OS to boot or whether to enter a recovery mode) and then loading the chosen kernel into memory so the OS can take over. It doesn’t configure BIOS settings—that’s handled by the system firmware (BIOS/UEFI). It also doesn’t run antivirus checks during startup; those checks are part of the OS or security software after the OS is up. And it doesn’t load user applications—the OS loads and starts user programs after it has booted.
