Why each option

NTFS is the only Windows-compatible file system that supports the Encrypting File System (EFS), which enables file and folder encryption.

AFAT

FAT does not support file-level security attributes or EFS, so encryption of individual files and folders is not possible.

BEXT4

EXT4 is a Linux file system and is not installable or usable as a Windows XP system volume.

CFAT32

FAT32 lacks the NTFS security descriptor model required by EFS and therefore cannot support file or folder encryption.

DNTFSCorrect

NTFS provides the security descriptor and access control infrastructure required by EFS (Encrypting File System), which is the Windows XP mechanism for transparent file and folder encryption. FAT-based file systems lack the security attribute support that EFS depends on, making NTFS the mandatory choice for encryption.
