The Mac OS Extended (Journaled, Encrypted) file system, also known as HFS+ (Hierarchical File System Plus), is the file system most commonly associated with Mac OS for volume management, particularly in versions prior to macOS High Sierra. This file system supports features essential for macOS, such as journaling, which helps protect the file system integrity by keeping a log of changes not yet written to the main part of the disk. Additionally, the encrypted aspect of this file system enhances security by protecting data with encryption, making it suitable for sensitive information.

Unlike the other options, which serve different purposes or are designed for compatibility with other operating systems, Mac OS Extended is specifically tailored for macOS environments. FAT, NTFS, and ExFAT are primarily used in Windows or cross-platform usage scenarios; therefore, they lack several native functionalities required for optimal performance in macOS volume management. The features of Mac OS Extended (Journaled, Encrypted) enable a more efficient and secure handling of files on macOS systems, reinforcing its suitability as the correct answer.
