A customer wants to make sure the data is protected and secure on a Windows laptop's hard drive. Which of the following is the best solution?

Windows Backup creates copies of data for recovery purposes but does not encrypt the primary data on the hard drive for security against unauthorized access.

BitLocker is a full-disk encryption feature included in Windows that encrypts the entire operating system volume and other fixed or removable data drives. This encryption ensures that data stored on the hard drive remains protected and unreadable to unauthorized individuals even if the laptop is stolen or accessed offline, making it the best solution for data security.

Shadow Copy (Volume Shadow Copy Service) creates point-in-time snapshots of files, primarily for data recovery or restoration, not for encrypting the data at rest to prevent unauthorized access.

A Trusted Platform Module (TPM) is a hardware component that provides security functions like storing cryptographic keys, but it is a prerequisite or enhancement for BitLocker, not a standalone solution for data encryption.
