A Windows user wants a filesystem that protects confidential data from attackers who have physical access to the system. Which of the following should the user choose?

EFS (Encrypting File System) is a feature of Windows that provides filesystem-level encryption. It is designed to encrypt files and folders to protect them from unauthorized access, even if an attacker has physical access to the computer.
* ext: A filesystem type used primarily in Linux, without native encryption features for Windows.
* APFS: Apple's filesystem, used in macOS and iOS.
* FAT: A simple filesystem type with no encryption features.
