Explanation

EFS (Encrypting File System) is a feature built into Windows NTFS that encrypts files and folders on disk using cryptographic keys tied to user accounts. When data is ciphered (encrypted) on a disk using a key, that is precisely what EFS provides. exFAT (A) is a lightweight filesystem designed for flash drives and external storage with no built-in encryption. HFS (B) is Apple's Hierarchical File System used on older macOS systems and also lacks native key-based encryption as a filesystem feature. FAT (C) is a legacy filesystem with no encryption capabilities whatsoever.
