Why each option
EFS (Encrypting File System) is the Windows file system feature that provides integrated, transparent encryption-based security at the file and folder level.
CDFS (CD-ROM File System) is a read-only file system for optical discs and provides no access control, permissions, or encryption security features.
EFS is built into the Windows NTFS architecture and provides integrated security by transparently encrypting files and folders using public-key cryptography, ensuring that only authorized users holding the correct certificate and private key can access the plaintext data - making security inseparable from the file system itself.
HPFS (High Performance File System) was developed for IBM OS/2 and, while it improved on FAT, it does not provide integrated encryption or modern access-control security.
FAT32 is a legacy file allocation table file system with no built-in support for file permissions, access control lists, or encryption.
