Why each option

BitLocker is a full disk encryption feature that protects data at rest, preventing unauthorized access to files stored on a drive even if the operating system is bypassed or the drive is moved to another computer.

Athe operating system from overwriting protected sectors on the hard disk drive.

BitLocker encrypts the entire drive, but its primary function isn't to prevent the OS from overwriting protected sectors; rather, it's to encrypt all data within those sectors.

Bunauthorized users from accessing the Internet.

BitLocker is a disk encryption technology and has no function related to controlling Internet access for users.

Cunauthorized access to files.Correct

BitLocker Drive Encryption protects data by encrypting entire volumes on a hard drive, ensuring that unauthorized users cannot access files stored on the drive without the correct encryption key, even if they attempt to boot from another OS or remove the drive. This full-disk encryption prevents data theft or exposure from lost, stolen, or improperly decommissioned computers.

Dprograms from accessing the memory of other programs.

BitLocker operates at the disk level and does not manage memory access permissions between programs; that is typically handled by the operating system's memory management unit.
